3/4 Flat Washers (ASME B18. 22.1)

Flat Washers, or just Plain Washers, are a flat annulus or ring, often of metal, used to spread the load from the head of a screwed fastening to the base material. Flat washers are used to increase the bearing surface of a nut or fastener's head thus spreading the clamping force over a larger area.
