  1.    How about the layer protection performance of Hexagon Socket Head Bolt? Let's take a look at it together.   The thickness of the electro-galvanized layer is usually 5-15μm, and the hot-dip galvanized bolt layer is generally above 35μm, even as high as 200μm. Hot-dip galvanized bolts have good coverage, dense coating and no organic inclusions. The anti-atmospheric corrosion mechanism of zinc includes mechanical protection and electrochemical protection. Under atmospheric corrosion conditions, there are protective films of ZnO, Zn(OH)2 and basic zinc carbonate on the surface of the zinc layer, which can slow down the corrosion of zinc to a certain extent. This layer of protection When the membrane (also called white rust) is damaged, a new layer will be formed. When the zinc layer is seriously damaged and the iron substrate is endangered, zinc will produce electrochemical protection to the substrate. The standard potential of zinc is -0.76V, and the standard potential of iron is -0.44V. When zinc and iron form a microbattery, zinc is dissolved as an anode. It is protected as a cathode. Obviously, China Stud Supplier's hot-dip galvanized bolts have better atmospheric corrosion resistance to the base metal iron than electro-galvanized.

  3.   Question: The company wants me to purchase a batch of hexagonal bolts. I don't know what is the difference between inner hexagonal bolts and outer hexagonal bolts?   Answer: Weigao China Stud Supplier is an enterprise specializing in the production of high-strength bolts and nuts. Recently, many netizens have called to inquire about the difference between the inner hexagon bolt and the outer hexagon bolt. In order to let everyone better distinguish the difference between the two, we will give an introduction. 1. Compared with the outer hexagon bolts, the installation space of the hexagon socket bolts is much smaller. During the installation process, the hexagon socket bolts can be installed in a relatively deep part, so there is no need to spend a lot of space. For hexagonal bolts, the installation space occupied by this will be larger.   2. The hardness of the two is different. Generally speaking, the hardness of the inner hexagon bolt is higher than that of the outer hexagon.   3. The head of the hexagon socket bolt can sink into the part when it is installed, so it does not need to be exposed to the outside, not only does not affect other parts, but also makes the connection more beautiful.   4. The use environment requirements of the two are different. Generally speaking, hexagon socket bolts are more suitable for those who need frequent disassembly and limited space.    In addition, there is a big difference between the two installation methods. The outer hexagon bolts generally use radial rotation when installing, and the inner Hexagon Socket Head Bolt usually uses axial rotation.

    Setting Of Hexagon Socket Head Bolt

    China Stud Supplier's anchor bolts are heavy-duty fasteners used in various construction projects, such as connecting wood frames to concrete walls, anchoring shear walls, wall panels and other heavy construction projects. The anchor bolt has a threaded end that allows nuts or washers to be inserted into the end to fix the wall formwork and other building parts into the concrete slab foundation. Depending on the manufacturer, there are many types of anchor bolts, such as anchor bolts whose ends are bent into a hook shape. However, the most common type of anchor bolts are cast-in-place anchor bolts. The hexagon head bolt ends of cast-in-place anchor bolts are cast into wet concrete. Here are the materials you need and the steps on how to pour anchor bolts in concrete.   Step 1-Prepare the concrete form   Before installing the anchor bolts, please prepare the concrete formwork. Concrete formwork is a plank or steel plate used to hold concrete together during hardening and curing.   Step 2: Mark the concrete bolt position    Use a tape measure and pencil to mark the location of the anchor bolts in the concrete form. This mark will serve as a guide for placing the anchor bolt bracket. You need to mark the location of your anchor bolts correctly, because it is difficult to move the anchor bolts when they have been placed on dry and cured concrete.   Step 3-Install the anchor bolt bracket   In step 2, nail the anchor bolt holder directly to the top of the guide mark. Placing the anchor bolt holder on the guide mark will ensure that the anchor bolt holder is in the correct position where the anchor bolt will be inserted. In addition to serving as a positioning guide, the anchor bolt bracket also helps to keep the threads of the anchor bolts clean, prevent concrete splashing, and prevent thread damage.   Step 4: Install the anchor bolts    Use a wrench to screw the anchor bolt into the anchor bolt holder. The anchor bolts are provided with guide marks, which can be used to position the anchor bolts at an appropriate height. Screw in anchor bolts of required height and depth.   Step 5: Pour concrete    Slowly pour the concrete into the concrete form. Make the poured concrete flow onto the anchor bolts and stop pouring when it reaches the correct height relative to the concrete form   Step 6-Allow the concrete to dry   Before removing the Hexagon Socket Head Bolt holder, please dry the concrete first to ensure that the anchor bolts are not knocked down in place. The concrete bolt bracket can be removed by unscrewing the cover of the concrete bolt. The drying and curing time of concrete depends on the type of concrete mixture you are using.   Step 7-Delete specific forms   For wooden concrete formwork, please use a hammer, for steel plate concrete formwork, please use a heavy-duty wrench to remove the concrete formwork.

    The Relaxation Of China Stud Supplier Products

    Hexagon Socket Head Bolt may seem inconspicuous, but in fact it has a great effect. Compared with ordinary nuts, there is a ring of special engineering plastic inside the thread of the lock nut. It can be attached to the thread to make the internal and external threads of the nut squeeze the engineering plastic during the tightening process, thereby producing a stronger The reaction force, in this way, can greatly enhance the friction between the internal and external threads, thereby providing a great resistance to vibration. The general nut anti-retraction friction is related to the tightening pressure between the internal and external threads. What it relies on is actually the friction generated by the pressure coming after the screw is tightened, so as to prevent the return, but when the screw is slightly loose When the pressure is reduced, the anti-returning effect will be quickly lost. The locknut of China Stud Supplier fully solves this problem and has a strong anti-loose ability.

    Matters Related To Bolt Factory

    When you buy products, you generally pay attention to some product-related problems. For customers who are planning to purchase an automatic screwdriver, when we accept the inquiry, the most frequently encountered problems are the price of machinery and equipment, product quality, and whether to test the machine first. 1. The price of China Nut machine Most of the automatic screw-tightening machinery and equipment belong to non-standard automation products, which are customized according to the customer's regulations. Therefore, the price is asked at the beginning. This is not a good response for everyone. If the customer must ask for the price, then everyone will first let The customer presents some product materials. The design of the portable automatic screw machine is very simple, and the price is relatively simple. Generally, you can give an approximate price by showing the photos of our products and the specifications of the applied screws. For the automatic automatic screw machine, the design plan is very complicated. It must be designed and manufactured according to the customer's product structure. You must show the product design structure, the total number of screw holes, the position of the screw hole, and the depth, diameter, and design plan near the wire hole. For materials such as processing technology regulations, it is best to show the test product back. We can design a plan according to the specific situation, and work out a solution and cost. Refer to "Factors influencing the price of automatic locking screw machine" 2. Product quality of automatic locking screw machine With the help of Jianfeng's overall scientific research strength, at this stage, it has its own R&D department, production and processing plant and manufacturing workshop, which can independently develop and manufacture the core components of automatic screw-tightening machinery and equipment, such as screw feeders, electric screwdrivers, etc. , The electronic components are all imported originals, and long-term cooperative relationships have been established with distributors. The products have undergone layer-by-layer inspections and comply with ISO9001: 2008 quality system management to ensure the quality of automatic locking screw machines and equipment. They are recognized by many customers in the industry . 3. Can the automatic locking screw machine be tested? The customer clearly proposed the test machine, mainly to grasp the quality of the product, and whether the characteristics of the product can be considered for its manufacturing requirements. Portable automatic locking screw machine because of its strong practicability, generally if the size of the screw is considered, everyone can show the details of the test product for customers around Shenzhen or other provinces with overall strength; for vertical automatic locking screw machine or platform automatic locking screw For machinery and equipment, you must customize samples according to the specific conditions before you can test the machine. Therefore, you must communicate with the machine before you want to test the machine, so that you can easily customize the product that is suitable for the customer. The key to Bolt Factory’s top shows that customers often ask many questions about the automatic locking screw machine. Naturally, there are many other problems, such as delivery date and settlement method. The delivery date must be based on the complexity of the product and the order information date table. To be clear, the settlement method must be communicated with everyone. Because non-standard automated machinery and equipment are different from general standardized automated machinery and equipment, the whole process of purchasing will be relatively complicated. We hope that everyone will understand, and will do a good job at each stage, and provide thoughtful service to many customers.

    The Purpose Of China Nut

    China Nut is a groove machined on the top of an ordinary hex nut (referring to the six sides of the nut), and each of the six sides has a groove. China Nut is used in conjunction with bolts with holes and split pins to prevent the bolts with holes from rotating relative to the China Nut. The purpose of China Nut is to fix the front and rear axles of the vehicle by tightening the screws on the front and rear axles, thereby fixing the frame and tires together. To fix the China Nut, the split pin must pass through the middle of the axle screw. Usually, it is necessary to drill the axle screws at both ends. The diameter of the hole and the groove width and depth of the China Nut In order to select the specifications of the cotter pin, when the selected wheel axle screw and cotter pin are more compatible with the China Nut, the nut will pass the front wheel fixing frame through the axle screw and the cotter pin. Hole fasteners for the axle screws. Hold the China Nut so that it will not loosen even when the vehicle is driving. China Nut does not have a unified national standard. They are usually used in the cabinet and sheet metal industries. The thickness of the hex nut is relatively thick, and is usually used in occasions where assembly and disassembly are often required. The thickness of the hexagonal nut is thin, and it is mainly used in occasions where the surface space of the connecting parts is limited. It is also often used as a lock nut to prevent the main nut from loosening. Hexagon socket nuts are specially designed for use with bolts with holes at the end of the screws. Therefore, split pins can be inserted into the holes of the screws from the grooves of the nuts to prevent the nuts from loosening automatically. It is mainly used for vibration load or alternating load occasions. Bolt Factory's China Nut is now used in many industries. Today, with the development of technology, the performance of products has been greatly improved. At present, many manufacturers produce this product. In order to make it more convenient for users to use, they need to read the relevant instructions before use.

    Features Of Hexagon Socket Head Bolt Plating

    1. Thickness of plating layer of Hexagon Socket Head Bolt In the electroplating process of threaded fasteners, whether barrel plating or rack plating is used, the thickness of the plating layer obtained by each fastener in a batch of products is different, that is, the plating layer distribution on the same fastener is also uneven. of. For example, the coating thickness of the thread crest is thicker than the pitch diameter and the bottom of the tooth, and the coating thickness of the two ends of the screw and bolt is thicker than the middle, and it becomes more significant as the length to diameter ratio increases. The same is true for nuts.Due to the shielding effect of the nut electroplating process, the thickness of the electroplating layer on the internal thread is very thin.Only the first buckle at both ends is thicker than the middle part, which is equivalent to the hex wrench surface thickness.   2, how to describe the plating thickness of a batch of threaded fasteners   In view of the uneven distribution of the plating thickness of threaded fasteners, the standard quoted four definitions of plating thickness, namely "nominal plating thickness", "batch average thickness", "local thickness" and "effective plating thickness". "Nominal plating thickness" refers to the nominal plating thickness of threaded fasteners and cannot represent the actual plating thickness. The actual plating thickness of threaded fasteners is described by "effective plating thickness". "Effective coating thickness" includes two aspects of "batch average thickness" and "local thickness". The plating thickness of threaded fasteners cannot be represented by the plating thickness of a part. Regardless of the threaded fasteners processed by rack plating or barrel plating process, each part in the same batch of parts cannot reach the same plating thickness, but the thickness The change obeys the normal distribution. We assume that the thickness of the coating is evenly distributed on the surface of the batch of parts to calculate the average thickness of the coating. This leads to the concept of "batch average thickness", which can be used to describe the entire batch. The coating thickness of the batch of threaded fasteners. The "batch average thickness" in standard table 1 is a range. The minimum batch average thickness is to ensure the anti-corrosion requirements of the threaded fasteners, and the maximum batch average thickness is to ensure the screwability of the threaded fasteners after plating.  China Stud Supplier's "local thickness" in the standard actually refers to the minimum local thickness, and the minimum local thickness describes the minimum specified value of the coating thickness that the threaded fastener should reach on the specified local test surface. The data verified by the test shows that the local coating thickness values measured on the specified local test surfaces of screws, bolt heads and screw, bolts, and nuts are all greater than the average thickness of the batch, which is usually the average thickness of the batch. The value meets the requirements, and the minimum local thickness can also meet the requirements. The test results also confirmed that the numerical relationship of "nominal coating thickness", "batch average thickness" and "local thickness" is correct, which constitutes the theoretical basis for the detection and acceptance of the plating thickness of threaded fasteners.
  9. China Stud Supplier introduced that the wet oxidation reaction carried out under high temperature and high pressure can be divided into two stages, which are controlled by the mass transfer of oxygen and controlled by the reaction kinetics, and temperature is the key influencing factor of the whole WAO process. The higher the temperature, the faster the chemical reaction rate, and the increase in temperature can also increase the oxygen mass transfer rate and reduce the viscosity of the liquid. The main function of pressure is to ensure the liquid phase reaction and keep the partial pressure of oxygen within a certain range to ensure a higher dissolved oxygen concentration in the liquid phase. After quenching, it is slightly oxidized and the surface is black, but there is no oxide scale. When the mesh belt furnace is used for mass production of fasteners, especially water-based media, the head or the whole blue and black oxidation phenomenon often occurs. This is because the workpiece generates a large amount of water vapor during the process of infiltration of water from the blanking material, and the surface oxidation of the workpiece intensified under the high temperature and high humidity oxidizing atmosphere. (1) Increase the water pressure of the water seal and try to avoid water vapor entering the furnace body; (2) Clean the filter; (3) Lower the level of the tank liquid; (4) Strengthen stirring. Increase the cooling rate. (5) Methanol contains excessive water content, replace qualified products Severe oxidation after quenching. There is oxide scale peeling off Hexagon Socket Head Bolt oxidation is serious after quenching, and even oxide scale peeling off, it can basically be determined that it is caused by the heating atmosphere. (1) The carrier gas (methanol) is used up, resulting in no atmosphere protection in the furnace; (2) The furnace body is leaking, and quickly check the air tightness; (3) The methanol water content exceeds the standard seriously, replace qualified products.

    Cleaning Of China Stud Supplier Products

       Hexagon Socket Head Bolt generally goes through the cleaning process in the process of manufacturing. In such a necessary link, due to improper methods and other reasons, some problems occurred in the fastener manufacturing process. Here, fastener manufacturers will introduce the problems that are more likely to occur when cleaning fasteners. We want to talk about the problems of cleaning after quenching. For the formal production process, after the fastener is quenched, it is necessary to use a solution with silicate for cleaning, and then rinse it. At this time, an operator is required. Take it very seriously, because if you are not serious at this time, some dirt will remain on the fasteners, so such fasteners are products of substandard quality.   China Stud Supplier For this part of the next introduction, although it is somewhat out of touch with cleaning, it also needs to use a solution for soaking. That is to say, when the fastener is tempered, it will inevitably fade. After such a situation occurs, the better treatment is to use ether for soaking. However, oily residue will also appear in this way. The reason for this is that the fasteners are unreasonably piled up during heating, so that the oxidation state during the quenching process occurs.

    China Stud Supplier Moisture-proof Operation

    If the Hexagon Socket Head Bolt gets wet, or is drenched in liquid, or is re-damp, etc., it is very likely to rust. So how to solve the waterproof and moisture-proof screw? Here is a brief introduction to the method: (1) As far as possible, use active solvent paint for vibrating machinery. (2) Use prepreg paint without air oxidation, such as epoxy-urethane-based or Epoxy-based prepreg. (3) When applying melamine prepreg paint to China Stud Supplier, the drying temperature and drying time should be adjusted. The drying temperature should be slightly higher than 130℃ (such as 135℃) and the drying time should exceed 180min. , It is necessary to strictly abide by the processing technology, especially in the high temperature and humidity season. Due to the awareness of anti-rust treatment, the paint drying (drying) time required in the paint factory's sample plate is not necessarily sufficient. The electric motor has an actual essence. (4) Choose fiberboard nail paint without volatile acid. (5) Choose paint with good hydrolysis resistance.
  12.    Hot-dip galvanizing Hexagon Flange Bolt water washing, hot-dip galvanizing is also called hot-dip galvanizing and hot-dip galvanizing: it is an effective metal anti-corrosion method, mainly used for metal structure facilities in various industries. It is to immerse the derusted steel parts in the molten zinc solution at about 500℃ to make the surface of the steel parts adhere to the zinc layer, so as to achieve the purpose of anti-corrosion.   1) The steel pipe should be washed in a flowing clean water tank. When washing, the steel pipe should be completely immersed in water, and the pickling strap should be relaxed, and the pickling strap should be lifted and dropped three to four times.    2) After washing, the water in the steel pipe should be cleaned, and solvent treatment should be carried out as soon as possible to prevent oxidation of the steel pipe.   3) The iron salt content standard of the cleaning water should not exceed the standard, no other debris, and keep it clean and transparent.   4) When washing the Threaded Rods And Eye Bolts, the operator is strictly prohibited from crossing the pickling tank to prevent slipping or falling into the acid tank to hurt people.

  16. Hexagon Socket Head Bolt is widely used in automotive, aerospace, construction and other fields, and it occupies a very important position in our lives. With the continuous development of the times, we will see that customers’ quality requirements are gradually increasing. Manufacturers During production, non-destructive testing is included as an important process flow, so that it can be more intuitive to detect whether there is damage or defect phenomenon and deal with it in time. So do you know what methods are available for non-destructive testing of fasteners? 1. Magnetic particle testing: According to the GJB 2028A-2007 "Magnetic Particle Testing" standard, magnetic particle testing can find surface and near-surface defects (such as cracks, inclusions, hair lines, folds, pores, looseness, etc.), and can visually display the shape of the defect. Position and size, and can roughly judge the nature of the defect. It has high detection sensitivity. The detectable defect is as small as 1μm in width. As long as the appropriate magnetization method is adopted, almost every part of the surface can be detected. Not only the detection speed is fast, but also the operation is convenient and the cost is low. It is especially suitable for detecting various surface and near-surface longitudinal defects of ferromagnetic materials. The main limitation of magnetic particle detection is that it can only detect ferromagnetic metal materials, and cannot detect non-magnetic materials such as austenitic stainless steel, aluminum, copper, magnesium, and titanium. The sensitivity of magnetic particle inspection has a great relationship with the magnetization direction. If the defect direction is parallel to the magnetization direction, or the angle with the surface is less than 20°, the defect will be difficult to appear, shallow scratches on the surface, and deeper holes are not easy Check it out. 2. Penetration inspection: According to the GJB 2367A-2005 "Penetration Inspection" standard, penetration inspection can detect surface opening defects of various non-porous materials. The inspection results are not affected by shape, size, organization structure, chemical composition and defect orientation. Influencing, the defect display is intuitive, the detection sensitivity is high (detectable defects of 0.5μm in width, 10μm in depth, and about 1mm in length), and defects in various directions can be checked at one time; due to the fast penetration detection speed, batch inspection can be carried out at the same time; suitable for inspection Various surface opening defects. The above points are summarized for everyone about the methods commonly used by China Stud Supplier in non-destructive testing of fasteners. These methods can help manufacturers find defects in products during the production process and ensure that every product sold The quality of a product can meet the needs of users, so that customers can be assured of quality and recognized by manufacturers.
  17.   Hexagon Socket Head Bolt has uniform force, can withstand high temperature and high pressure, and is easy to install, so it is necessary to work under high temperature and high pressure, such as marine oil bolts, chemical equipment bolts, pressure pipe bolts, etc. Used for some bolts. This is Hexagon Socket Head Bolt. Hexagon bolts usually only have a fixing function and are used in places that do not need to withstand high temperatures and pressures. The Hexagon Socket Head Bolt national standard has very clear requirements for the selection, manufacture, inspection and packaging of Hexagon Socket Head Bolt. According to various industry standards for processing and manufacturing for different industry applications. For example, the petrochemical Hexagon Socket Head Bolt is manufactured according to petrochemical industry standards HG20613 and HG20634. Using high-quality high-strength alloy steel as raw materials, strictly abide by the production standards and regulations. When you leave China Stud Supplier, the inspection department will perform a factory inspection. Ensure product quality.
  18. T-bolts can be directly inserted into the aluminum profile groove. It can be automatically positioned and locked during installation. It is usually used with flange nuts. When the angle is installed, it is a standard matching connector. It can be selected and used according to the width of the contour groove and different series of contours. T-bolts are movable anchor bolts. So, what should you pay attention to when installing T-bolts? Below weigao Industrial Bolt Factory will take you to find out. 1. Before installing the direct-buried bolts, you must be familiar with the drawings and understand the geometric dimensions, position and height of each bolt and bolt frame. Before construction, put each bolt and bolt frame in place at each construction position, and verify that the number and geometric dimensions of a batch of parts are consistent with the drawings. 2. Designate a person to be responsible for listing and checking the construction quality, size, elevation and axis position of the bolt frame installation. 3. During the construction process, first of all, the field welding of the bolt frame should have higher standards and strict requirements. For welding requirements, the integrity of the weld must be checked and accepted according to the acceptance specification. In terms of controlling the geometric size between each bolt, the reinforcement must be welded and fixed to ensure that it is not easy to move when the concrete is poured. 4. After fixing each bolt, use the instrument to combine its elevation dimension to make it correct. After the bolts are all fixed in place, use bolt sleeves or tape to protect each bolt thread. 5. When pouring and tamping concrete, do not cut the pump tube directly above the bolt. Avoid the use of bolts and bolted frames. After pouring the concrete, the geometric size, axis position and height of the bolts should be checked again. If China Stud Supplier finds any displacement, it should be corrected in time to prevent the equipment from being unable to be installed in the future.

    Main Materials Of China Nut

       Stainless steel China Nut's selection requirements are that the main material is stainless steel, which is not easy to rust. In fact, stainless steel is a part of stainless steel, which has both acid resistance and corrosion resistance. The rust and corrosion resistance of stainless steel is caused by the formation of a chromium-rich oxide film (passivation film) on the surface of the stainless steel. The rust resistance and corrosion resistance are relative. Tests show that the corrosion resistance of steel in weak media such as atmosphere, water and nitric acid increases with the increase of the chromium water content in the steel. When the chromium content reaches a certain percentage, the corrosion resistance of steel will suddenly change, that is, from easy to rust to not easy to rust, and from corrosion resistance to corrosion resistance. There are many ways to classify stainless steel. Classified by room temperature structure, there are martensite, austenite, ferritic and duplex stainless steels. According to the main chemical composition, it can basically be divided into two systems: chromium stainless steel and chromium nickel stainless steel. According to the application, it can be divided into nitric acid-resistant stainless steel, sulfuric acid-resistant stainless steel, seawater-resistant stainless steel, etc., and divided into pitting-resistant stainless steel and stress-corrosion-resistant stainless steel by type. Corrosion resistance can be divided into non-magnetic stainless steel, free-cutting stainless steel, low-temperature stainless steel, high-strength stainless steel and so on. Due to its excellent corrosion resistance, formability, compatibility and toughness in a wide temperature range, stainless steel has been widely used in heavy industry, light industry, occupation of daily necessities and architectural decoration.       Austenitic stainless steel       Stainless steel with austenitic structure at room temperature. When the content of Cr is about 18%, Ni is 8%-10%, and C is about 0.1%, the austenite structure is stable. Austenitic Cr Ni stainless steels include the famous 18Cr-8Ni steel and high Cr Ni series steels. These steels are developed by increasing the content of Cr and Ni and participating in elements such as Mo, Cu, Si, Nb, and Ti. Austenitic stainless steel is non-magnetic, with high toughness and plasticity, but low strength. It cannot be strengthened by phase change. It can only be strengthened by cold working. If you participate in s, CA, Se, TE and other elements, it has excellent free cutting ability. In addition to its oxidation resistance in acidic media, if stainless steel contains Mo, Cu and other elements, it can also resist corrosion by sulfuric acid, phosphoric acid, formic acid, acetic acid and urea. If the carbon content of this steel is less than 0.03% or contains Ti and Ni, the intergranular corrosion resistance can be significantly improved. High-silicon austenitic stainless steel with concentrated nitric acid has excellent corrosion resistance. Due to its comprehensive and excellent induction function, austenitic stainless steel has been widely used in various industries.       Ferritic stainless steel      In the state of use, it is mainly stainless steel with ferrite structure. The content of chromium is in the range of 11% to 30% and has a BCC crystal structure. This steel usually does not contain nickel, and sometimes contains small amounts of Mo, Ti, Nb and elements. This kind of steel has the characteristics of large thermal conductivity, small expansion coefficient, good oxidation resistance, and strong stress corrosion resistance. It is mainly used to make parts resistant to atmospheric, water vapor, water and oxidizing acid corrosion. This steel has some disadvantages, such as poor plasticity, significantly reduced plasticity and corrosion resistance after welding, which limit its use. Using AOD or VOD can greatly reduce void elements such as carbon and nitrogen. Therefore, the stainless steel standard parts of Bolt Factory have been widely used.

    Special Customization For China Stud Supplier

    Non-standard screws are screws whose specifications are not within the national standard. Do you know why there are non-standard screws? Today weigao Industrial Bolt Factory will explain to you the reasons for non-standard screws. 1. Environmental restrictions. For example: (M9×1) threads can be tapped in a 10×1 pipe. 2. Corporate behavior. For example: the lock bed of a household sewing machine is (M5×1) thread. Non-standard screws of China Stud Supplier need to be customized. GB screws do not need to be made to order, generally as long as the specifications are matched, they can be used. Commonly used national standard specifications are everywhere on the market. Another point is to be explained; national standard screws also have non-optimal products, which are also to be customized. Because there are not many people who use it, the manufacturer does not stock it.
  22. Stainless steel screws refer to the shape of screws that are punched with stainless steel screw wire, and then threaded. Stainless steel screws can be seen everywhere in our lives.

    What Products Does China Stud Supplier Have

       1. The screw of the Industrial Bolt Factory is a tool used to tighten the machine parts of the appliance according to the physical and mathematical principles of oblique circular rotation and friction of objects. Screw is a general term for fasteners and is used every day. Generally speaking, micro screws are essential industrial necessities in daily life: for example, cameras, glasses, wall clocks, electronic devices, etc. use the least screws. General purpose screws used in televisions, electrical products, musical instruments, furniture, etc.; and large screws, screws, nuts used in engineering, construction and bridges; vehicles, airplanes, etc. Trams, cars, etc. use large and thin screws. Screws have important tasks in industry. As long as there is industrial production on the earth, the function of screws is permanent. Screws are one of the great creations of mankind, bringing convenience and convenience to mankind's production and life.      2. China Stud Supplier standard parts refer to commonly used parts, such as threaded parts, keys, pins, rolling bearings, etc., whose structure, dimensions, drawings, markings, etc. have been fully standardized and are produced by professional factories. Generally speaking, it includes standardized fasteners, connectors, transmission parts, seals, hydraulic parts, pneumatic parts, bearings, tension springs and other mechanical parts. In a narrow sense, only standard fasteners are included. Standard parts, which are usually called standard fasteners in China, are abbreviated as narrow concepts, but the existence of broad concepts cannot be eliminated. In addition, there are professional standard parts, such as automobile standard parts, mold standard parts, hydraulic standard parts, engineering machinery, etc., which are also general standard parts.
  25. 1. Screw strength When Industrial Bolt Factory chooses furniture screws, it must pay attention to the overall strength of the screws. Strength refers to the ability to resist pressure. Because in the process of using furniture screws, we need to use devices and equipment to push the furniture into the wooden side. If the strength of the furniture screw is low, deformation will occur, which may also affect the quality of the entire furniture. Therefore, high-strength furniture screw Shape products must be purchased. 2. Wear resistance and corrosion resistance According to the furniture screw manufacturer, since the technology and raw materials of each furniture screw are very different, their wear resistance is also different. When buying furniture screws, you can conduct wear resistance experiments. Products with strong wear resistance will not have obvious scratches when they are scratched by abrasive products. Anti-corrosion refers to furniture screws have strong corrosion resistance, can resist acid and alkali corrosion, and furniture screws brand products have a long service life. 3. Aesthetics China Stud Supplier is very strict when choosing, because they need to match the whole home style, and some furniture needs to choose invisible screws to avoid screws affecting the appearance quality, which is an aspect that needs to be paid attention to. Be careful when choosing furniture screws. Aesthetic screw products can be considered as the enhancement of the entire furniture color, and the furniture is pushed to a higher level.
