The steel flat washer has a black oxide finish and meets American Society of Mechanical Engineers ASME B18.22.1 specifications. The flat washer provides a bearing surface for fastener load distribution or is used as a spacer between components. Steel is often used in applications where strength is the primary consideration. The black oxide finish offers mild corrosion resistance and lubricity. Washers distribute the load of a fastener across a surface and can also be used as spacers, springs, shims, or locking devices. Several different washer styles fit a variety of application and installation requirements. The most common style is a flat washer. More specialized washers provide additional benefits. A cup washer, for example, helps protect fasteners from electrical currents, while a lock washer offers additional security in an assembled workpiece.
