Heavy Duty Flat Metal Washers Plate Round Carbon Steel Prevent Loosening / Leaks

Flat washers are usually thin pieces of various shapes to reduce friction, prevent leaks, isolate, prevent loosening, or distribute pressure. This material is used in many materials and structures to perform a variety of similar functions. Due to the limitations of the material and process of the threaded fasteners, the bearing surfaces of the fasteners such as the bolts are not large, so that the surface of the parts to be joined is protected to reduce the compressive stress of the bearing surface, and washers are used. In order to prevent loosening of the connection pair, loose-proof spring washers and multi-tooth lock washers, round nut stop washers and saddle-shaped, corrugated, conical elastic washers are used.
Flat washers are mainly used to reduce the pressure. When some parts are tightened with large axial forces, the washers are easily pressed into a dish shape. In this case, the material can be changed and the hardness can be improved.
