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.
18-8 stainless steel washers have good chemical resistance and may be mildly magnetic.
Washers that meet ASME B18.21.1 adhere to strict dimensional standards.
