Flat Pad

Flat washers are usually thin parts of various shapes, used to reduce friction, prevent leakage, isolate, prevent loosening or disperse pressure. This kind of parts are found in many materials and structures, and are used to perform various similar functions. Due to the material and process limitations of threaded fasteners, the bearing surface of fasteners such as bolts is not large, so washers are used to reduce the compressive stress of the pressure-bearing surface and protect the surface of the connected parts.
