Basic Information

Flat washers are usually thin pieces of various shapes to reduce friction, prevent leaks, isolate, prevent loosening or spread pressure. This component is found in many materials and structures to perform a variety of similar functions. Limited by the materials and processes of threaded fasteners, the bearing surfaces of fasteners such as bolts are not large. Therefore, in order to reduce the compressive stress of the pressure bearing surface to protect the surface of the connected component, a washer is used. To prevent the loosening of the connection pair, anti-loose spring washers and multi-tooth lock washers, round nut stop washers, and saddle-shaped, wave-shaped, and tapered elastic washers are used.

The flat washer is mainly used to reduce the pressure. When the axial force of some parts is large, it is easy to press the washer into a dish shape. At this time, it can be solved by using materials and increasing the hardness.
