The combination screw includes a head, a threaded section and a flanging section, the flanging section is arranged below the threaded section, and the flanging section and the threaded section pass through the mounting holes on the fittings, so that the combination screw and the fittings are rotatably connected, so After the flanging section passes through the fitting, the bottom of the flanging section is riveted and pressed so that the bottom of the flanging section is turned outward, so that the combined screw cannot be separated from the fitting.

An anti-loosening nut structure includes a flat nut and an oblique nut. One end surface of the oblique nut is an oblique surface, and an angle is formed between the oblique surface and the vertical line of the screw hole axis of the oblique nut. Nuts are installed on the bolts one after another, and the mating contact surfaces of the two nuts include the inclined surface, which are tightened in sequence.

Bolt material: 18Cr2Ni4W, 25Cr2MoV steel; bolt specification: M27~M48. Because this kind of steel is easy to form a passivation film on the surface, and this passivation film will make the bolt unable to obtain a good adhesion chemical nickel phosphorus layer, so special pretreatment measures must be taken to remove the film first, and measures should be taken To prevent its regeneration, it is possible to ensure a good bonding force between the plated coating and the substrate. At the same time, due to the large geometric size of the bolt, it increases the difficulty of nickel-phosphorus plating treatment and quality inspection of the process.

A rivet is a nail-shaped object with a cap on one end: in riveting, the parts being riveted are joined by their own deformation or by interference. There are many types of rivets, and they are informal. However, the two ends of conventional rivets are concentric, which is not suitable for special occasions.

Swimming self-locking nut GJB 125.1~125.6-86 The double-ear sealing swimming self-locking nut is composed of four parts: sealing cover, self-locking nut, pressure ring and sealing ring. It has compact structure and reliable sealing, and is suitable for products whose working pressure is not more than 2atm, working medium is gasoline, kerosene, water or air, and the operating temperature is -50~100℃. However, it has certain difficulties in the manufacturing process and air tightness test.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: fine thread bolts, GB862.2 metal washers, metric thread lock nuts, aluminum special nuts and other products, we can provide you with suitable products for you.
