Oversized Washers
Compared to our general purpose washers, these have exaggerated diameters and/or thicknesses for covering oversized holes or for use as spacers and levelers.
Brass washers are corrosion resistant in wet environments, nonmagnetic, and electrically conductive.

SAE Washers
SAE washers generally have a smaller ID and OD than USS washers.
In addition to resisting rust in wet environments, copper and brass washers are electrically conductive. Nickel-plated brass washers are also nonmagnetic and have a decorative finish.
