Machine Screw Washers

Machine screw washers are made with smaller outside diameters to be used with machine screws, but they are also used in many other applications where large diameters just don’t work. They are most commonly supplied in low carbon steel with a zinc plating, but they are also available in stainless steel, brass, and other materials and finishes.

Check our chart of standard sizes. Special dimensions are also available on request.
