Your go-to metal washer for every screw size. Washers take the pressure off nuts and screws to protect mounting surfaces.

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.
