Steel Flat Washer Zinc Plated Finish ASME B18-22-1 Type B 1-2 Screw Size 17-32 ID 1-3-4 OD 0-100 Thick Pack of 10

The steel flat washer with type B tolerance has a zinc plated 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 zinc plating offers corrosion resistance and has a reflective appearance. It is Type B for tighter tolerances than Type A washers. 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.
