Internal-/External-Tooth Lock Washers
Manufacturer part: 90416A116
Grip tighter than split lock washers to prevent nuts and screws from loosening in applications with constant movement, such as conveyors. Tooth lock washers typically can't be reused because the teeth often get bent when tightened.Internal and External Tooth—The strongest hold of all our tooth lock washers, these combine internal and external teeth to boost gripping power. However, the teeth may mar your material and snag on objects. Pair these washers with fasteners that are large enough to make contact with the external teeth, such as pan, button, and binding head screws.Black-Oxide Steel—Typically chosen for their appearance, these washers have a dark, matte coating that creates a finished look. They offer minimal corrosion resistance, so they're best for dry environments.
