Small Parts Brass Flat Washer, Plain Finish, No. 4 Screw Size, 0.12" ID, 9/32" OD, 0.025" Thick (Pack of 100)

The brass flat washer has a plain finish. The flat washer provides a bearing surface for fastener load distribution or is used as a spacer between components. Brass provides corrosion resistance and offers thermal and electrical conductivity. The material is nonmagnetic.

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.
