Summary of information:We have more than ten years of production experience in the screw industry, the main products are: thick washer washers,...

Fasteners are a class of mechanical parts that are used for fastening connections and are widely used. It is used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemical industry, metallurgy, mold, hydraulic and other industries, in various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemicals, instruments And supplies, etc., you can see all kinds of fasteners, which are widely used mechanical basic parts. In the fields of listed rails, construction machinery, etc., due to the harsh application environment, the requirements for fasteners are more stringent. If the fasteners are loosened, it may lead to serious consequences, resulting in a large amount of property damage, even serious life cost.

Bolts are widely used in the machinery industry. Round head bolts are generally fixed in equipment parts, but during long-term use, due to external force or vibration of the equipment itself, the bolts are loosened, and the bolt heads have a long-term use process. A fatal disadvantage is that it is prone to slippage, which can cause major safety hazards and economic losses to users in severe cases.

The core rivet is another type of single-sided riveting. When riveting, the head of the rivet is hit with a hammer to expose the core, so that it is flush with the end face of the nail head, that is, the riveting operation is completed, which is very convenient, especially suitable for inconvenient Riveting occasions using ordinary rivets (which must be riveted from both sides) or blind rivets (lack of a rivet gun). Usually use flat head rivets, countersunk head rivets are suitable for occasions where smooth riveting is required on the surface.

At present, in the standard cabinets of computers, networks, automation, etc., to fix the equipment in the cabinet, it needs to be fixed by using fasteners. The nuts in the existing fasteners are ordinary nuts, which are internal card structures. , there are the following shortcomings: 1. The installation and disassembly are complicated, and a large amount of force is required to insert the nut during installation and disassembly, and the nut cannot be installed and disassembled at all due to the processing error of each nut; 2. After the nut is used for a long time, the nut The card edge will have slack problem, which will affect the use; 3. Installation or disassembly is easy to cause problems such as falling, which may cause electrical short circuit, etc., and there are potential safety hazards; 4. The efficiency of equipment installation is low.

High-strength bolt connection has the advantages of simple construction, good mechanical performance, disassembly and replacement, fatigue resistance, and no loosening under dynamic load. It is a promising connection method. High-strength bolts use a special wrench to tighten the nut, so that the bolt generates a huge and controlled pre-tension. Under the action of pre-pressure, a large frictional force will be generated along the surface of the connected parts. Obviously, as long as the axial force is less than this frictional force, the components will not slip and the connection will not be damaged. This is the high-strength bolt connection. principle. High-strength bolted connections rely on the friction between the contact surfaces of the connectors to prevent them from sliding each other. In order to make the contact surfaces have sufficient friction, it is necessary to increase the clamping force of the components and increase the friction coefficient of the contact surfaces of the components. The clamping force between the components is achieved by applying pretension to the bolts, so the bolts must be made of high-strength steel, which is why it is called high-strength bolted connections. In high-strength bolted connections, the friction coefficient has a great influence on the bearing capacity. Tests show that the coefficient of friction is mainly affected by the form of the contact surface and the material of the components. In order to increase the friction coefficient of the contact surface, methods such as sandblasting and wire brush cleaning are often used to treat the contact surface of the components within the connection range during construction.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: half countersunk head screws, AS1110.1 screws, DIN6915 hexagon nuts, percussion flat caps GB109 rivet iron natural color GB867 round head rivets and other products, We can provide you with the right fastener solution for you.
