  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.

    The Production Materials Of China Stud Supplier

    If the iron high-precision bolts and studs are wetted, or drenched in liquid, or are re-moisturized, etc., they are very likely to rust. So how to solve the Hexagon Socket Head Bolt? Here is a brief introduction to the method: (1) As far as possible, use active solvent paint for vibrating machinery. (2) Use prepreg without air oxidation, such as epoxy-urethane-based or Epoxy-based prepreg. (3) When applying melanoic acid prepreg paint, 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 be strict Comply with the processing technology, especially in the high temperature, humid and cold season, the vibrating screen, from the awareness of anti-rust treatment, the paint drying (drying) time required in the paint factory's template is not necessarily sufficient, and the motor has practical The essence of it. (4) Choose fiberboard nails without volatile acid paint. (5) China Stud Supplier selects paint with good hydrolysis resistance.
  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.

    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.

    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.
  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.
