Product  Description

Square  flat  washers are usually thin pieces of various shapes, used to reduce friction, prevent leakage, isolate, prevent loosening or dispersing pressure. They are found in many materials and structures to perform similar functions. Limited by the material and process of threaded fasteners, the bearing surface of bolts and other fasteners is not large. Therefore, in order to reduce the pressure stress on the bearing surface and protect the surface of connected parts, washers are used. In order to prevent the looseness of the connecting pair, spring washer, multi tooth lock washer, round nut stop washer, saddle shaped, wave shaped and cone-shaped elastic washer are used.

It can produce elastic deformation under various loads, so as to effectively fasten and seal, prevent water leakage, water seepage and shock absorption and buffer of the building structure. Most of them are used in construction sites.
