Split Lock Washers
As a screw is tightened, these washers flatten to add tension to the joint, counteracting fatigue around the joint from small amounts of vibration. This makes them a common choice to prevent fasteners from loosening. However, they resist the least amount of vibration compared to other locking washers.
These washers are compatible with fasteners that have right-hand threads to prevent loosening. The uneven split ends bite into fasteners for a tight grip, but they won’t work with hardened surfaces. These washers hold better than curved or wave washers. They are not reusable after tightening.
Black-oxide steel washers are mildly corrosion resistant in dry environments.
316 stainless steel washers have excellent resistance to chemicals and salt water. They may be mildly magnetic.
18-8 stainless steel washers have good chemical resistance and may be mildly magnetic.

Split Lock Washers for Socket Head Screws
Also known as high-collar lock washers, these have a smaller outside diameter than standard split lock washers to fit neatly under socket head cap screws.

Belleville Spring Lock Washers
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.

Spring Lock Washers for Slotted Bearing Nuts
Designed for use with bearing nuts, these lock washers have a conical shape that presses like a spring against bearings, bushings, gears, and pulleys to hold them in place on your threaded shaft or spindle. They also have an inner tab that sits in the shaft or spindle’s keyway to prevent the nut from loosening.
Steel washers are strong and flexible.
Stainless steel washers are more corrosion and chemical resistant than steel washers.

Internal-Tooth Lock Washers
Internal teeth dig into the screw head while the smooth outside edge won't snag objects. These washers provide greater vibration resistance than split lock washers. Use with fasteners that have small heads, such as fillister and cheese head screws.

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.
