Originally designed for the automotive industry, these washers conform to SAE sizing standards. They generally have smaller diameters than USS washers to fit in cramped spots and are thinner to create more precise gaps. Washers distribute pressure under screws and nuts to protect your mounting surface.
Zinc-Yellow-Chromate-Plated Steel—With the same corrosion resistance as zinc-plated steel, these withstand occasional exposure to moisture.
High Strength Fastener—About 25% stronger than medium-strength steel washers, these are commonly used when fastening components in valves, pumps, and motors. Pair them with other high-strength steel nuts and bolts.
For Fastener Strength Grade/Class—If you require screws or nuts with a specific fastener strength rating, make sure your washer matches the grade or class.
