All-aluminum blind rivet The body of the rivet is also made of high-quality aluminum wire, which is beautiful and durable after riveting and will never rust: Compared with ordinary blind rivets, rivets have lower riveting strength and are suitable for connectors with relatively soft materials. . Split Stainless Steel Rivet: This rivet is a high-tension, corrosion-resistant choice. Round head rivets are mainly used in riveting occasions subject to large lateral loads, and are the most widely used. Flat cone head rivets are often used in riveting occasions with strong corrosion such as ship hulls, boiler water tanks, etc.
Guangdong Yueluo Hardware Industry Co., Ltd. provides a screw positioning pin, which is composed of a main body part and an insert part. The main body part is a circular boss structure, and the bottom of the circular boss structure is provided with a rectangular groove. The inserting part is fixed on the middle part of the upper surface of the main body part, the lower part of the inserting part and the contact section of the main body part are in a circular truncated structure, the upper part of the inserting part is a cylindrical structure, and the outer surface of the cylindrical structure is provided with threads; the screw positioning pin , The structure is simple and the design is ingenious. The special structural design of the main part and the insert part can be positioned between the punch and the die in the first processing process, effectively reducing the gap formed during the processing between the punch and the die. Firmly fixed, suitable for the needs of large-scale industrial production.

In chemical production equipment, the cylinder body and the head cover need to be connected and sealed. The traditional sealing structure is to connect the two with a screw, add a non-metallic gasket in the middle and fix it with a nut. However, such a sealing structure only controls the tightening torque, and has the technical defect that the sealing ring will be twisted or even broken during repeated loading and unloading of the cylinder head cover, resulting in poor sealing performance.
The self-tapping locking screw is a series of coarse thread and ordinary thread, and the thread size is M3~M12mm. The threaded rod of the self-tapping locking screw is a thread with an arc-shaped triangular section. The screw is surface hardened and can be screwed into a prefabricated hole of black or non-ferrous metal material (which can be made by drilling, punching or die casting), and extruded to form an internal thread. The threaded rod portion can be made into a cylindrical or triangular shape with a diameter equal to or less than the circumscribed circle. Self-tapping locking screws have low screw-in torque and high locking performance. The varieties of self-tapping locking screws in the product standard of Chinese commodity fasteners include GB/T6560 (cross-recessed pan head), GB/T6561 (cross-recessed countersunk head), GB/T6562 (cross-recessed half-sunk head), GB/T6563 ( Hexagon head), GB/T6564 (hexagonal flower-shaped cylindrical head) five series. Self-tapping locking screws are generally fastened with pneumatic or electric screwdrivers. Most of the automotive industry uses hexagonal head, cross recessed pan head and hexagonal socket head self-tapping locking screw with high fastening efficiency.
