Copper Round Flat Washer, Copper Steel Flat Washer

A copper flat washer is a flat disc with a centrally located hole. Copper round flat washers are used to provide a bearing surface to minimize surface wear. They also evenly distribute a fastener’s load to minimize surface deformation from fastener tightening or can cover large clearance holes. Copper is non-magnetic, corrosion resistant alloy that has the best electrical and heat conductivity.
