    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.
  2.    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.

  6. 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.
  7.   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.
  8. 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.
  12. 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.
  15. 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.

    Forming Of Industrial Bolt Factory Thread

      Industrial Bolt Factory's bolt threads are generally cold worked, so that a thread blank within a diameter range is passed through a wire plate (die), and the thread is formed by the pressure of the wire plate (rolling die). The plastic streamline of the thread part is not cut, the strength is increased, the precision is high, and the quality is uniform, so it is widely used. In order to produce the thread outer diameter of the final product, the required thread blank diameter is different, because it is limited by the thread precision, whether the material has coating or not. Rolling (rolling) threading refers to a processing method that uses plastic deformation to form thread teeth. It uses a rolling (rolling board) mold with the same pitch and tooth profile as the thread being processed. While extruding the cylindrical screw blank, it rotates the screw blank, and finally transfers the tooth shape on the rolling mold to On the screw blank, the thread is formed. The common point of rolling (rubbing) thread processing is that the number of rolling revolutions does not need to be too much. If it is too much, the efficiency is low, and the surface of the thread is prone to separation or random buckling.    Conversely, if the number of revolutions is too small, the thread diameter of China Stud Supplier will easily become out of round, and the initial pressure of rolling will increase abnormally, which will shorten the life of the mold. Common defects of rolled threads: cracks or scratches on the surface of threaded parts; random buckles; threaded parts out of round. If these defects occur in large numbers, they will be discovered during the processing stage. If the number of occurrences is small, these defects will circulate to users without noticing the production process, causing trouble. Therefore, the key issues of processing conditions should be summarized, and these key factors should be controlled in the production process.
  17. 1. From the perspective of raw materials: China Stud Supplier's high-strength bolts and nuts are made of high-strength materials. 2. From the perspective of intensity level: it is increasingly widely used. Two strength levels of 8.8s and 10.9s are commonly used. 3. From the point of view of the force characteristics of Industrial Bolt Factory: applying pre-tension and transferring external force by friction. Ordinary bolted connections rely on bolt shear resistance and hole wall pressure to transmit shear force. Its influence can be ignored. In addition to its high material strength, high-strength bolts and nuts also exert a large pretension on the bolts, which causes squeezing force between the connecting members, so that there is a large friction force perpendicular to the screw. Moreover, the pre-tension, anti-slip coefficient and steel type directly affect its bearing capacity.

    How Does Fasteners Suppliers Avoid Biting?

    Do you know how to avoid the seizure of stainless steel screws and stainless steel nuts? Today Stud Manufacturer-weigao will explain to you how to avoid the seizure of stainless steel screws and stainless steel nuts. Generally, stainless steel screw manufacturers do not recommend the use of stainless steel screws and stainless steel nuts together. Due to the material of stainless steel, stainless steel screws are often seized after they are tightened with stainless steel bolts and stainless steel nuts during the assembly of low-temperature pipeline flanges. It is difficult to remove it. So if stainless steel screws are used in conjunction with stainless steel nuts, which aspects should we solve the seizure state? 1. Cryogenic treatment can be done to intrude stainless steel screws into a low-temperature liquid nitrogen box for a certain period of time to reduce the deformation caused by temperature differences and metallographic changes, thereby improving the sealing performance of the valve at low temperatures. 2. Change the stainless steel nut to other materials, or change the basic one to other materials. This avoids the seizure of stainless steel bolts and stainless steel nuts. 3. At present, there is a technology that can prevent the screw and the nut from biting. 4. When Fasteners Suppliers uses stainless steel screws and stainless steel nuts, apply some grease on the stainless steel screws to avoid the phenomenon of stainless steel screws seizing.
  19. Now there are many different shapes and sizes on the market, which are used for connection or fastening. We call it a screw for short. Screws are most often contacted in daily life with wall nails (dry wall nails). Screws have many uses, but do we know how a small screw is produced? Today, we will walk into weigao Fasteners Suppliers to understand how the little things we most often contact were born. In fact, the raw materials used to produce screws are the ones that most affect the quality and life cycle of the screws. It's like having no fresh meat and vegetables, giving you the best knives and chefs, and you can't make a table of delicious and delicious dishes. The same goes for screws. Brushing teeth Walking into the workshop, our master is cold-drawing the round steel we purchased back into steel wire. The next step is to start the head. The master told us that different screws have different heads, so we need to Adjust the mold on the punching machine so that the nail embryo can be produced. Now the screw is just a rudiment; the next step is to rub the teeth. Just like the head, you need to adjust the thread shape of the rubbing plate to rub the thread. Heat treatment is needed, carburizing, quenching, and tempering are required to complete the heat treatment. The last step is to plate or phosphatize the color. Such a complete screw is completed. However, phosphating is generally required, and most of them are wallboard nails (drywall nails). Because wallboard nails (drywall nails) are mostly used to connect gypsum boards, Stud Manufacturer generally only need phosphating. The colors of other general self-tapping screws are relatively rich. For self-tapping screws, different factories have different requirements.

  21. Standard parts refer to the commonly used components such as screw parts, keys, pins, rolling bearings, etc. which have been fully standardized in structure, size, drawing method, marking, etc. and are produced by professional Bolt Factory. The standard parts are mainly three materials: carbon steel, standard parts stainless steel, and copper. Here is a brief introduction to these three materials: 1. Carbon steel: low carbon steel, medium carbon steel, high carbon steel, alloy steel. Second, stainless steel: mainly divided into martensitic stainless steel, austenitic stainless steel, ferritic stainless steel, etc. 3. Copper: The commonly used materials are brass and zinc-copper alloy. (Mainly use H62, H65, H68 copper as standard parts.) Nanjing Standard Parts    The standard parts are mainly considered from the following aspects when selecting materials: 1. Requirements for standard parts materials in terms of mechanical properties, especially strength; 2. The requirements of working conditions on the corrosion resistance of the material; 3. The requirements of the working temperature on the heat resistance (high temperature strength, oxidation resistance) of the material; 4. China Nut's production process requirements on material processing performance; 5. Other factors, such as weight, price, and procurement must be considered.

    How Should Full Threaded Stud Be Checked?

    Fasteners indicate that the Full Threaded Stud generally goes through the cleaning process during the manufacturing process. However, in such a necessary link, due to improper methods and other reasons, some problems occurred in the production process of Full Threaded Stud. Here, the following small editor introduces the problems that are relatively easy to occur when cleaning the fullthreshold study. We want to talk about what will happen to the cleaning after quenching. For the normal production process, after quenching, the full threshold study will use a solution with silicate for cleaning and then rinse. At this time, the operator needs to carry out the cleaning very carefully, because if he is not careful at this time, some dirt will remain on the full threshold study. Then such full threshold study is a product with substandard quality. For this link introduced next, although it is somewhat out of touch with cleaning, it also needs to be soaked with a solution. That is to say, when the Full Threaded Stud is tempered, fading will inevitably occur. After such a situation occurs, the better treatment method is to soak with ether. However, oil-like residues will also appear in this way. The reason for this is that the Full Threaded Stud is not stacked properly during heating, resulting in oxidation during quenching. As far as the current situation is concerned, the difference between Full Threaded Stud and standard parts is not big. the Full Threaded Stud manufactured according to the technical standards is the standard Full Threaded Stud, sometimes abbreviated as Full Threaded Stud. The standard fullthreaded study is an important category of standard parts. Full Threaded Stud is now basically a standard part, and is also a standard part for fastening classes. Most of the standard parts are Full Threaded Stud, but the range of standard parts is larger. Therefore, their business scope is basically the same. At present, many people have combined the Full Threaded Stud with standard parts. Full Threaded Stud is a general term for a type of mechanical parts used when two or more parts are tightly connected into a whole. It is also called standard parts in the market. Therefore, people need not stick to the difference between the two all the time, but only need to use it appropriately.
  23. Welding nut is a nut suitable for welding outside the nut.It is generally made of a weldable material and is thicker and suitable for welding.Welding is equivalent to turning two separate pieces into a whole, melting the metal at high temperature and mixing After cooling together, the alloy will be added in the middle, the internal is the role of molecular force, and the strength is generally greater than the strength of the parent body. The welding parameter experiment depends on the fusion size of the weld, and the welding parameter is adjusted according to the fusion size until the defect is eliminated. Of course, the quality of welding is related to pre-welding treatment, such as cleaning, oil stains, etc. There are many factors that affect the welding quality of projection weld nuts.For China Stud Supplier, there are mainly: the material of projection weld nuts, the form and size of projections of projection weld nuts, and the surface cleanliness (natural color plus appropriate anti-rust treatment); In the welding process of projection welding nuts, the most important thing is to control three process parameters: electrode pressure, welding current and welding time. The increase in electrode pressure causes the bumps to collapse instantaneously, the weld nugget size decreases or even disappears, and the joint strength decreases, destroying the stability of the welding process; the electrode pressure is too small, on the one hand, the bumps cannot be crushed, on the other hand The welding process produces splashes. The welding current should be properly matched with the welding time. Generally, the harder specifications are used when the diameter of the nut bump is large, and the soft specifications should be used when the diameter of the bump is small.   Sometimes we often encounter the problem that the M6 welding nut is not welded well. The material we are using now is Baosteel 1008. And the meat of the fillet is not less. For this problem, the main reason is that the two materials should be similar, preferably the same, and the quality of the electrode used. There are many factors that affect the welding quality of projection weld nuts.For Industrial Bolt Factory, there are mainly: the material of projection weld nuts, the form and size of projections of projection weld nuts, and the surface cleanliness (natural color plus appropriate anti-rust treatment); In the welding process of projection welding nuts, the most important thing is to control three process parameters: electrode pressure, welding current and welding time.

    Commercial Supply Of China Nut

    The standard parts produced by Bolt Factory are similar to machine screws, but the thread on the screw is a special thread for self-tapping screws. It is used to fasten and connect two thin metal components into one piece. Small holes need to be made on the components in advance. Due to the high hardness of such screws, they can be directly screwed into the holes of the components. It is also similar to machine screws, but the thread on the screw is a special thread for wood screws, which can be directly screwed into a wooden component (or part). It is used to connect a metal (or non-metal) part with a through hole to a wooden component Tighten together. This connection is also detachable. It is a type of fastener composed of two parts, the head and the screw. It can be divided into three categories according to the purpose: machine screws, set screws and special purpose screws. The machine screw is mainly used for a tightly threaded part and a fastened connection between a part with a through hole, which does not require a nut fit (this form of connection is called a screw connection and is also a detachable connection; it can also It is used with nuts to fasten the connection between two parts with through holes.) Set screws are mainly used to fix the relative position between two parts. Special purpose screws such as eye bolts are used for lifting parts. With internal threaded holes, the shape is generally a flat hexagonal column, or a flat square column or a flat cylinder. It is used with bolts, studs or machine screws to fasten and connect two parts into one piece. overall. With the increase in international exchanges, the development of imported mold localization and the requirements of foreign-funded enterprises for the international standards of their supporting molds, on the one hand, attention has been paid to adopting international standards or foreign advanced national standards as far as possible in the formulation of standards, including the adoption of advanced Enterprise standards; on the other hand, many mold standard parts manufacturing companies produce mold standard parts according to Chinese standards, and also produce mold standard parts according to the standards of advanced foreign companies. Standard parts are an important part of the mold and the basis of the mold. It has very important technical and economic significance for shortening mold design and manufacturing cycle, reducing mold production cost and improving mold quality. The experience of foreign industrial developed countries proves that the professional production and commercial supply of China Nut has greatly promoted the development of the mold industry.
  25. The main purpose of China Nut is to fasten utensils and parts. It is mostly used in mining, metallurgy, textile, transportation machinery, etc. It is generally suitable for occasions requiring simple equipment and parts, has a certain degree of self-alignment, is easy to follow, has a double-structured sealing device, and works in harsh environments. China Nut is the tightening principle of screws. Most fasteners are used between the shaft and the sleeve to prevent the shaft and the sleeve from changing their position during use. They can be used to prevent relative movement between the shaft and the sleeve, and some The top thread is used for easy disassembly. For example, the two parts are tightly coupled and can be separated by the top thread. China Nut has a wide range of uses. Although the screws are small, the effect is not small.
