Hex Nut Manufacturer introduces how to avoid bolt dislocation:
1. On symmetrical high-strength bolt products, in order to avoid making mistakes in bending, an asymmetrical precise positioning hole can be installed.
2. When bending, the rough surface of high-strength bolt products should face the bending bearing as far as possible to prevent the Mao Kou from being torn due to tensile force. If it is not allowed, it is necessary to set up a
processing hole to take this opportunity to locate it accurately. Rolling and hemming are all unique curved rolling holes. The nominal diameter size depends on the thickness of the raw materials of rolled steel parts. The nominal
diameter of thick steel parts should be larger, generally, d>1.5. It is not necessary to set the centerline of the curling at the center of the metal sheet. If the plane of the metal sheet is set at the tangent position of its cylinder,
it is more economical to manufacture.

Due to the practical characteristics of the bolt itself and other problems, the outer diameter of the threaded tooth is small, and there are ordinary bolts, and when the outer diameter is small, the outer diameter of the tooth will slide. At present, the stud bolt manufacturer has improved the thread sliding solution, standardized the use of the thread, selected the appropriate thread, customized or purchased the appropriate thread, and used high-quality bolt materials, which made the thread more rigid. And the stud bolt manufacturer has assembled the high-strength bolt connection, and the high-strength bolt connection pair is assembled at both ends. Next, Hex Bolt Manufacturers describes how to improve the thread sliding problem.
For the stud bolt manufacturer’s products, whether the processing temperature of the product is too low or the heating temperature is too low, the springback cannot be reduced well after bending. The heating temperature is too high, and the surface of the workpiece is too large, which will affect the surface of the workpiece. quality. After quenching, the workpiece may be deformed. In order to reduce deformation, use oil as cooling water during quenching, choose a slower cooling rate and reduce the internal stress of the workpiece to reduce the deformation of the workpiece after quenching. The production practice of the effect of the above-mentioned processing technology is completely feasible. With the advancement of science and technology, the requirements for materials are getting higher and higher.
Currently, standard parts have their own requirements for the production of raw materials, most of which are made of steel wire or steel. Stud bolt manufacturers can use them to produce stud bolts and other fastening parts, especially according to the strength requirements and material corrosion resistance requirements under working conditions. The materials that meet the applicable requirements are selected according to relevant national standards. The length of the screw is not enough and the hardness is not enough to withstand the corresponding torque. The torque that cannot withstand the strength of the screw and the appropriate torque result in insufficient combination with each other.

Hex Nut Manufacturer introduces the blackening reasons and treatment methods of stainless steel screws:
The blackening of stainless steel screws is usually caused by high heat generated during cold heading or threading. Usually occurs in the cross groove part. During the production process, the supply of lubricating oil can realize the
timely distribution of heat, and the speed of the machine can also be appropriately reduced to avoid problems. Of course, in addition to technical reasons, the blackening of stainless steel screws may also be caused by the material
problems of the stainless steel screws themselves.
The solution process for the blackening of stainless steel screws: degreasing-water passing-cross tank cleaning agent-water passing-neutralization-water passing-drying; heating the stainless steel screw cross tank cleaning agent to 70
degrees, and then degreasing After the stainless steel screw products are put into the cross-slot cleaning agent, soak for 5-15 minutes, pass in clean water, neutralize, and blow-dry.

2H Heavy Hex Nuts Manufacturer introduces the sealing form of fasteners:
1. Cazali seal: This is a forced seal, and there are three forms: externally threaded Cazali internal seal, internally threaded Cazali internal seal, and improved Cazali internal seal.
2. Fastener external thread clamp: commonly used internal end face seal. Its washer is a triangular soft metal washer made of copper or aluminum. The cylinder flange and the container end cover are connected through a threaded sleeve, the compression bolt is tightened to apply force to the compression ring, and the compression gasket is sealed to achieve sealing.
3. Fastener internal Ghazali seal: the working principle of internal thread Ghazali seal is basically the same as that of external thread, except that the threaded end cover is indirectly screwed into the end of the cylinder with internal thread. The gasket is placed at the connection between the end cover and the tail of the cylinder, and a pressure ring is arranged on the gasket.
4. Improved Kazzari seal: The improved Kazzari end face seal structure does not require a threaded sleeve to connect the end cover and the cylinder but uses a bolt connection. Other parts are similar to the external threaded Kazzari end seal. It has no obvious advantages, so it is difficult to adopt.
5. Fastener flat gasket seal: this is a mandatory seal. Washers made of soft material or metal are placed between the connecting surfaces. Under the action of the pre-tightening force of the bolt, the uneven part of the contact surface (that is, the gap or hole where the medium may leak) is extruded and filled with the plastic deformation gasket material, so as to achieve the purpose of the container.

China Hex Bolt Manufacturers introduced what causes the quality factors of screws to encounter?
1. The screw head is deformed and the head is skewed. The possible cause is improper installation of the first punch of the screw mold and improper adjustment of the machine.
2. The head of the screw is not round. The reason is the improper selection of the first die of the screw die or the insufficient filling of the first die.
3. The screws have burrs or burrs. The reason is that the first punch is poorly formed, which is mainly caused by the excessive gap between the punch rod and the die hole or the punch rod is too short.
4. The screw head is cracked, and the screw head has cracks. The reason may be that the quality of the screw wire itself is defective, so before the screw wire is headed, it must be inspected by the quality department and tapped with a lotion. Especially for stainless steel screw wire, it is necessary to check that it is stainless steel 201 and that is stainless steel 304. It may also be caused by the wrong use of a die, and the viscosity of the lubricating oil.

A screw is a tool that uses the physics and mathematics of the oblique circular rotation of the object and the friction force to gradually tighten the objects and parts. Screws are a common term for fasteners, an everyday spoken word. Screws are indispensable industrial necessities in daily life: extremely small screws used in cameras, glasses, clocks, electronics, etc.; general screws used in televisions, electrical products, musical instruments, furniture, etc.; as for engineering, construction, and bridges, large-scale screws are used. Screws and nuts; transportation equipment, airplanes, trams, cars, etc. are used for both large and small screws. Screws have important tasks in the industry. As long as there is an industry on the earth, the function of screws will always be important. The screw is a common invention in people’s production and life for thousands of years. According to the application field, it is the first invention of mankind. Next,Hex Bolt Manufacturers will introduce the parameters and characteristics of the screws:
1. Head type. This is easy to identify. It can be intuitively judged with the naked eye, such as a word head, or other head shapes.
2. Diameter. This is very accurate, which is difficult to judge with eyes. At this time, we often use vernier calipers to measure the length. Note that this diameter includes the length of the tooth.
3. Length. Also use a vernier caliper, note that this length does not include the length of the head.

According to China Hex Bolt Manufacturers , a welded nut is equivalent to combining two separate parts into a whole. The metal is first melted at a high temperature and then mixed together and then cooled. An alloy is added in the middle. Because of the internal molecular force, the strength is generally better than The matrix is strong. General nuts are usually used for thin-walled plates and are embedded by pressure, so the contact surface is the contact stress. In fact, the strength depends on the connector and the matrix. The nut is subjected to shear stress, so if the strength of the nut is not enough It will be broken by shearing, and if the strength of the matrix is not enough, it will be plastically crushed to deform and fail.
These two kinds of nuts each have their own advantages and disadvantages. For example, the welding nut has a relatively large strength and a wide range of use. The thickness can be freely controlled, but due to the high temperature, the connected parts will be deformed and cannot be disassembled. They are also lively Metals cannot be welded by conventional methods, such as aluminum, magnesium, etc., and shielding gas or argon arc welding is required. This requires clear processing technology and precision. Generally, nuts are simple to install and disassemble, easy to install and transport, so they are suitable for almost any Metal that can be punched, but its application range is relatively narrow, so it can only be used for thin-walled plates or sheet metal connections.
The material of the workpiece to be welded (same or different), by heating or pressurizing or both, and with or without filling materials, the process of making the material of the workpiece reach the atomic building and forming a permanent connection, welding nut It is a fastener with internal threads and used with bolts. A mechanical part that has internal threads and is used in conjunction with a screw to transmit motion or power.

Double-ended studs are mainly used where one of the connected parts has a large thickness, requires a compact structure, or is not suitable for bolt connection due to frequent disassembly. Next,China Hex Bolt Manufacturers will introduce the scope of application of double-ended studs.
1. It is usually used in places where one of the connected parts is too thick, inconvenient to perforate, and requires a compact structure. Blind holes must be used for connection or frequent assembly and disassembly.
2. Double-headed stud connection is to screw one end of the double-headed stud into the screw hole of one of the connected parts, and the other end through the through-hole of the other to be connected, then put on the washer and tighten the nut. This kind of connection is often used when one of the connecting parts is too thick or inconvenient to install and disassemble. When disassembling, usually only remove the nut but not the stud to prevent multiple assembly and disassembly from damaging the screw hole of the connecting piece.

Hex Nut Factory introduces the function and disassembly method of hexagon bolts:
The function of the hexagonal bolt is to fix the front axle and the rear axle by fastening screws passing through the front axle and the rear axle, thereby fixing the frame and the tires together. To prevent the nut from loosening, a split pin must pass through the slot of the slotted nut to fix the nut, and the split pin must pass through the middle of the shaft screw to fix the slotted nut.
How to remove the hexagonal bolt: For the connection where the head of the hexagonal slotted nut is slightly higher or flat than the plane of the fixing member, the hexagonal nut with the outer diameter slightly smaller than the head of the hexagonal slotted nut can be placed on the head of the hexagonal slotted nut, and then Spot weld the nut to the head of the hexagonal slotted nut. After cooling, you can tighten the nut with a movable hand and take out the hexagon socket bolt.

Hex Nut Factory introduced that stud bolts have adopted large-scale equipment in the process of product processing and manufacturing to improve the processing quality of stud bolts. If the joints are thicker and the studs are longer, we will use special equipment for processing. Now, we will use high-quality metal materials to process and manufacture studs. Then the better material selected has many application characteristics in addition to the characteristics of ordinary stud bolts.
With the continuous development of stud bolt technology, the problem of bolt manufacturing has been solved. Nowadays, people are concerned about the quality of the raw materials used for bolts. If the quality of the bolt line is not good, there will be a lot of impurities. If the bolt is not hard enough, there will be many serious problems in use. Of course, the problem is that there are more than three reasons for bolt damage, but the above two reasons are the main reasons for screw damage. If the bolt is found to be damaged, it can be inspected in stages to find out the cause and the stud bolt. This is also a type of screw. Stud bolts are divided into various specifications and sizes according to materials, uses and grades. They are called studs with four patterns at both ends.
The general reason for bolt damage is: over-tightening or using the torque of an adjustable wrench or a socket wrench, because it is usually clamped between the threads and locked during the manufacturing process. If a wrench or electric wrench is used, the nut needs to be rotated perpendicular to the axis of the screw, which is likely to cause damage to the bolt.

Hex Nut Manufacturers introduces three ways to tighten high-strength bolts:
1. Torque method
According to the closed system in which the torque M is proportional to the pre-tension, first, use a general wrench to tighten the nut starter, and then use a wrench with a visible torque value to tighten to the determined torque value.
2. Angle method
According to the close contact between the layers, the conversion angle of the high-strength bolt is directly proportional to the pretension of the bolt. When tightening, first use a short wrench to screw the nut to the untransformed position, and then use a long wrench to screw the nut to the determined position to reach the pre-tension.
3. Unscrew the tail of the bolt
For torsion shear-type high-strength bolts, this bolt has a special tail. When tightening, use a spanner to cover the bolt and the tail of the bolt, one sleeve rotates forward, and the other sleeve rotates. When the nut is tightened to a certain level, the end of the bolt is broken. Because the depth of the notch at the end of the bolt is determined by the closed relationship between the twisting torque and the pre-tightening force, the corresponding pre-tension value is reached when it is twisted off.

Hex Nut Manufacturers introduces how to use stud bolts. The rotation speed and force need to be moderate, not too large. Try to choose a wrench or socket wrench instead of an adjustable wrench or electric wrench. The speed is fast and the temperature rises sharply. The use of washers can effectively prevent excessive locking problems. Before choosing the product correctly, please make sure that the product has been manufactured. The mechanical properties of the product meet the needs of use.
Now, the non-slip studs (including the long bolts) have a partition in the middle. The diaphragm divides the long bolt into a front bolt and a rear bolt, and there is a diaphragm in front of the diaphragm. At present, by improving the stud bolts, it is not only convenient for assembly and maintenance, but also both sides will not loose or fall off, thereby protecting personal safety. Stud bolts have good anti-rust function, and double-headed
The length of the bolt is longer. Nowadays, stud bolts have become tools for processing and producing high-quality metal materials. In addition to the general characteristics of studs, high-quality materials with many application characteristics are also selected.
In production, there are many locking conditions between the thread teeth. However, the studs can also rust. Need to pay attention to the maintenance of the stud bolts in use. Locking and joining often occur on aluminum alloy and titanium alloy fasteners. These metal alloys themselves can prevent corrosion. In the case of surface damage, in the case of surface damage, the stud will also rust. A thin oxide layer is formed on the metal surface to prevent excessive corrosion.

The three-combination screw is mostly used for the connection between thin metal plates to play a connection role. When connecting, first make the bottom hole of the connecting piece, and then screw the combination screw into the bottom hole of the connecting piece. Due to the high hardness of the thread surface of the combined screw, the internal thread can be screwed into the bottom hole of the screw to be connected to form a connection.
Hex Nut Manufacturers introduced that the triple screw can be sucked up with a magnet, but the stainless steel triple screw is difficult to suck up. Environmental protection triple combination screws and non-environmental protection screws are invisible to the naked eye, and require mechanical testing, and cannot be judged out of thin air with the naked eye. The specifications of the three combination screws need to be judged by the national standard, and the salt spray machine can be used to measure how many hours the salt spray of the triple screw takes.
The material of the triple screw: It is decided to test the material of the combined screw wire with a testing machine, which is divided into iron and stainless steel. Iron wire is divided into 1010 wire, 1018 wire, and 10B21 wire; stainless steel is divided into stainless steel 201, stainless steel 304, and stainless steel 316. The classification of triple screws is based on the material of the screw wire and the hardness index of the screw wire. Generally, the materials of the three combination screws are divided into stainless steel and iron, and iron can be divided into low carbon steel, medium carbon steel and high carbon steel. Carbon steel composite screws refer to iron composite screws, generally divided into 4.8, 8.8, 10.9 and 12.9 levels.
However, the 10.9 and 12.9 combination screws are rarely used in the market, and among the three combination screws on the market, the 4.8 and 8.8 combination screws are commonly used. Grade 4.8 combination screws are usually made of screws and steel wire piers 1010A. After the screws and the line piers are made into screws, they are assembled together with elastic flat washers. After this 4.8 grade combination screw is manufactured, it does not need to be hardened, and its hardness can reach 4.8. The 8.8 grade combination screw is made of threaded 10B21 piers. After the screw thread piers are made into screws, they can be equipped with elastic pads and flat pads to combine three Rub the teeth together so that the elastic flat pad can be fastened to the screw, and the elastic flat pad will not fall off. After the combination screw is produced, it needs to be hardened to make its hardness reach 8.8, and then we need to electroplate it, in order to prevent the spring pad in the combination screw with a hardness of 8.8 from becoming brittle and easy to break. In this way, the hardened combined screw must be dehydrogenated, and then electroplating can be performed after dehydrogenation.

Due to the practical characteristics of the bolt itself and other problems, the outer diameter of the threaded tooth is small, and there are ordinary bolts, and when the outer diameter is small, the outer diameter of the tooth will slide. Nowadays, the thread sliding solution has been improved, the use of threads has been standardized, the appropriate threads have been selected, the appropriate threads have been customized or purchased, and high-quality bolt materials have been used, which makes the threads more rigid, and Hex Nut Manufacturers have been assembled High-strength bolt connection is used, and the high-strength bolt connection pair is assembled at both ends.
Regardless of whether the processing temperature of the product is too low or the heating temperature is too low, the springback cannot be reduced well after bending. If the heating temperature is too high, there are too many workpieces with surface oxides, which will affect the surface quality of the workpiece. After quenching, the workpiece may be deformed. In order to reduce deformation, use oil as cooling water during quenching, choose a slower cooling rate and reduce the internal stress of the workpiece to reduce the deformation of the workpiece after quenching. The production practice of the effect of the above-mentioned processing technology is completely feasible. With the advancement of science and technology, the requirements for materials are getting higher and higher.
Standard parts have their own requirements for the production of raw materials, most of which are made of steel wire or steel. They can be used to produce studs and other fastening parts, especially according to the strength requirements and material corrosion resistance requirements under working conditions. The materials that meet the applicable requirements are selected according to the relevant national standards. The length of the screw is not enough and the hardness is not enough to withstand the corresponding torque. The torque that cannot withstand the strength of the screw and the appropriate torque result in insufficient combination with each other.

Hex Nut Manufacturing Strategy
2021年2月25日The large torque of high-strength hexagon nuts is affected by many factors. To study the low-cycle fatigue performance of high-strength hexagon Hex Nut , high-strength hexagon nuts have a medium diameter, helix angle, and tooth angle. High-strength hex nuts have the greater elastic restoring force and equivalent friction angle. There will be some changes after repeated use. Therefore, high-strength hexagon nuts only need to analyze the law of large torque changes when the lock nut is subjected to cyclic load from these two aspects.
Magnetic methods are used to measure coating thickness. High-strength hexagon nuts are used for non-destructive measurement of the non-magnetic coating on the magnetic substrate using a magnetic thickness gauge. The microscopic method is called the metallographic method. High-strength hex nuts are strictly etched. The firmware is magnified on a metallurgical microscope with a micrometer eyepiece to measure the coating thickness of the part. Timing process method. The coating thickness of the high-strength hex nut is calculated based on the time required for the partial coating to dissolve. High-strength hexagon nuts also have electroplating drop method, anode dissolution coulometric method, and so on.

Unstandard fastener is the main basic product of the machinery industry, and the development of the machinery industry also puts forward higher requirements for fastener products. Domestic common standard fasteners have always been oversupply, while high-end fasteners (fasteners with high temperature, special-shaped, titanium-plastic composite, special performance, etc.) are in short supply and rely on imports. The State Machinery Bureau lists "common standard fasteners" as restricted development products, and "high-strength special-shaped fasteners" as currently encouraged development products.
With the improvement of national industrialization level and technological progress, the use of high-strength fasteners has gradually increased. The global economy continues to be sluggish and overseas export trade is sluggish. Many domestic and foreign fastener companies are facing severe tests. Accelerating economic transformation and structural upgrading is imminent, and opening up overseas markets is undoubtedly an important way out for the development of the current fastener industry.
From the fourth quarter of 2011 to the first half of 2012, affected by the objective environment, the development speed of the fastener industry may slow down, but starting from the third quarter of 2012, with the policy in place, the 18th National Congress of the Communist Party of China will be held, and A series of development policies to be launched will promote the further development of the industry.
Unstandard fastener and must insist on innovation and adjustment and transformation, and continue to rely on key industries such as automobiles, new energy, aerospace, shipbuilding, urban transportation, IT, electronic appliances, and construction to accelerate the optimization and upgrading of fastener products, and promote The firmware industry develops healthy and steadily. The global fastener market exceeds US$50 billion, and China’s total fastener output in 2012 is also expected to reach about 6.8 million tons. However, compared with manufacturing powerhouses such as the United States and Japan, there is still a big gap in my country’s fastener industry.https://www.ydfastener.com/products/unstandard-fastener/

Non-standard fasteners include: bolts, studs, screws, nuts, washers, and pins. Locking or seizure often occurs on fasteners made of stainless steel, aluminum alloy and titanium alloy. These metal alloys have anti-corrosion properties. When the surface is damaged, a thin oxide layer is formed on the metal surface to prevent Further corrosion.
When stainless steel fasteners are locked, the pressure and heat generated between the teeth will destroy this oxide layer, causing blockage or shearing between the metal threads, and then adhesion. When this phenomenon continues, the stainless steel fasteners will be completely locked and can no longer be removed or continued to be locked. Usually this series of blocking, shearing, adhering, and locking actions occur in just a few seconds, so a correct understanding of the use of such fasteners can prevent this phenomenon.
From the fourth quarter of 2011 to the first half of 2012, due to the impact of the objective environment, the development speed of the unstandard fastener industry may slow down.
