Flat cushion spring pad

A flat washer is mainly punched out of an iron plate, usually in the shape of a flat washer with a hole in the middle. The size specifications of this hole are generally determined according to customer requirements.

Flat washers are usually thin pieces of various shapes used to reduce friction, prevent leakage, isolate, and prevent loosening or dispersion of pressure. Many materials and structures contain this component, which is used to perform various similar functions. Due to the material and process limitations of threaded fasteners, the bearing surface of bolts and other fasteners is not large. Therefore, in order to reduce the compressive stress on the pressure bearing surface and protect the surface of the connected parts, washers are used. To prevent the loosening of the connecting pair, anti loosening spring washers, multi tooth lock washers, round nut stop washers, and saddle, waveform, and conical elastic washers are used.Flat washers are mainly used to reduce pressure
