The 18-8 stainless steel flat washer has a plain finish and meets Deutsches Institut für Normung DIN 125 specifications. The flat washer provides a bearing surface for fastener load distribution or is used as a spacer between components. The 18-8 stainless steel material provides strength and offers good corrosion resistance in many environments. The material may be slightly magnetic.

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.
