These washers have smaller outside diameters than standard spring lock washers to fit neatly under socket head cap screws. Also known as conical washers, these have a slightly cupped shape that gives them spring-like flexibility to grip tighter than split and tooth lock washers. They minimize loosening from wear, temperature changes, and vibration. Serrations on the top and bottom provide extra gripping power. Load-rated Belleville disc springs are also available.
Zinc-plated steel washers are corrosion resistant in wet environments.
18-8 stainless steel washers have good chemical resistance and may be mildly magnetic.

Also known as conical washers, these have a slightly cupped shape that gives them spring-like flexibility to grip tighter than split and tooth lock washers. They minimize loosening from wear, temperature changes, and vibration. Load-rated Belleville disc springs are also available.
Zinc-plated steel washers have an outer layer of zinc that protects the inner steel from rust in wet environments and extends the life of the washer.
For extra gripping power, use washers with a serrated top.

Wedge 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.
316 stainless steel and zinc-flake-coated steel washers are comparable to NORD-LOCK® Series washers.
Black zinc-flake-coated steel washers are comparable to Sherex TEC Series washers.
Spring lock washers are comparable to NORD-LOCK® X-Series washers. They withstand vibration better than standard wedge lock washers by combining the locking power of a wedge lock with the clamping force of a spring lock.
