    Mil. Spec. Tooth Lock Washers

    These washers are manufactured and tested to strict U.S. military standards for material and construction. They resist vibration better 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.

    Teeth on the outside edge bite into both the fastener and the mating surface for a stronger hold than internal-tooth lock washers. However, they may mar your material and snag on objects. Pair these washers with nuts and screws that are large enough to make contact with the teeth, such as pan, button, and binding head screws.
    Wear-Resistant 410 Stainless Steel—These grip hard material better than other types of stainless steel. They are not as corrosion resistant as 18-8 and 316 stainless steel, so they are best for environments that experience occasional moisture.
