Fasteners are a type of mechanical parts that are used for fastening connections and are widely used. They are used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, molds, hydraulics and other industries. This kind of fastener is a widely used mechanical basic part. It is characterized by a wide variety of specifications, different performance and uses, and a very high degree of standardization, serialization and generalization. Therefore, some people also refer to a type of fasteners with existing standards as standard fasteners, or simply as standard parts.

The force condition of the screw is broadcasted: 1) Self-weight G; 2) Torque M required to overcome material resistance; 3) Axial force P generated by material pressure. Screw screw screw is generally scrapped due to long-term wear, the gap between the screw and the barrel is too large and cannot be extruded normally, but there are also examples of damage due to improper design or improper operation. Therefore, the screw should also meet certain strength requirements. 4) The dangerous section of the screw is generally at the smallest thread root diameter in the feeding section. According to material mechanics, for plastic materials, the composite stress is calculated by the third strength theory, and its strength conditions are:

Nuts are a commonly used fastening parts and are widely used in various mechanical and electrical equipment. Common application equipment does not have particularly strict requirements on the anti-loosening properties of nuts, but for automobiles, high-speed railways, aerospace and nuclear power and other fields, many equipment or components work in a vibration environment for a long time, and it is easy to loose between bolts and nuts. This will affect the normal operation of the equipment and even cause safety accidents.

screw is a common connecting piece, a tool that uses the physical and mathematical principles of the circular rotation and friction of an object to fasten the parts of the object step by step. Screws are indispensable industrial necessities in daily life: tiny screws used in cameras, glasses, clocks, electronics, etc.; general screws in televisions, electrical products, musical instruments, furniture, etc.; as for engineering, construction, and bridges, large screws are used. Screws and nuts; transportation equipment, airplanes, trams, automobiles, etc. are used together with large and small screws. Screws have important tasks in industry. As long as there is industry on 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 a great invention of human beings. A traditional screw is generally set as a screw head at one end and a screw rod at the other end, which cooperates with an external nut to fasten the connector between the screw head and the nut. However, such as some home appliance modules, chassis and other electrical appliances, the modules and boxes fixed by traditional screws often fasten many parts together by screws. During maintenance, it is necessary to disassemble all parts of the maintenance part, which is very troublesome. Therefore, a new type of screw structure that can be connected at both ends and can realize layered installation is required. During maintenance, only the connecting layer of the maintenance part needs to be disassembled, and neither the exterior nor the interior needs to be disassembled.

The traditional single-sided riveting process mainly adopts two methods: rivet nut connection and blind rivet connection. The efficiency of the rivet nut is low. If the hollow nut is used, the rigidity is insufficient, resulting in low connection strength. In addition, the torsion resistance of the rivet nut is low. If the rivet nut is used to obtain better torsion resistance, it is made into a hexagonal shape. Embedding, because the shape of the sheet metal opening also needs to be made into a corresponding hexagon, it is inconvenient to process.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: GB37 pressure plate bolts, flat head bolts, countersunk nuts, 10.9 fishtail bolts and other products, we can provide you with suitable tightening bolts. Firmware Solutions.
