Also known as NORD-LOCK® washers, these two-piece washers provide more locking power than split, tooth, and spring lock washers. Wedges on the inside lock the two pieces together, and serrations on the exterior grip surfaces to resist loosening from high vibration and shifting. Washers are reusable.

316 stainless steel washers have excellent resistance to chemicals and salt water. They may be mildly magnetic.

Zinc-flake-coated steel washers are corrosion resistant in wet environments.
