This specification covers round and miscellaneous shape steel plain (flat) washers furnished in an unhardened condition. The washers are intended for general use bolt, nut, and stud applications to provide increased bearing surface, spacing, and to prevent galling. The washers shall be punched from hot-rolled, hot-rolled and pickled, or cold-rolled steel; or shall be machined from bar stock or tubing; or shall be forged. The washers shall also be tumbled, vibrated, or otherwise processed to minimize burrs. These washers may be zinc-coated, hot-dip-coated, cadmium-plated, or zinc-plated by using hot dipping, mechanical deposition, and electroplating processes. Chemical analysis may be conducted in order to determine the composition of washers and a hardness test may also be performed.
