Rivets are widely used in the fixing of product components, and the process of inserting rivets into products is currently mostly done by manpower. However, relying on manpower to insert rivets has low automation and low efficiency, which is not conducive to large-scale Production.
Such flat gaskets typically include passage openings for fluids through which fluid can flow from one side of the flat gasket to the other side of the flat gasket.

By adopting the above technical solution, the setting of the pin cap allows the user to conveniently drive the pin into the pin hole of the workpiece by using a hammer and other power-assisted equipment. Pin hole, the plane of the top contact body relative to the pin cap will collide with the plane where the pin hole is located, the convex body and the pin hole are tightly squeezed, and the pin cannot fall off.
Gaskets are divided into: flat washer - grade C, large washer - grade A and C, extra large washer - grade C, small washer - grade A, flat washer - grade A, flat washer - chamfer type - Grade A, high-strength washers for steel structure, spherical washers, cone washers, square bevel washers for I-beam, square bevel washers for channel steel, standard spring washers, light spring washers, heavy spring washers, internal tooth lock washers , Internal serrated lock washers, external serrated lock washers, external serrated lock washers, single-ear stop washers, double-ear stop washers, outer tongue stop washers and stop washers for round nuts, etc.
