Mil. Spec. Internal-Tooth Lock Washer
Manufacturer part: 96551A240
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. Internal Tooth—Internal teeth dig into the nut or screw to prevent it from backing out. Unlike external-tooth lock washers, these have a smooth outside edge, so they are less likely to mar your material or snag on objects. However, they don’t grip quite as well. Pair them with fasteners that have small diameters, such as fillister and cheese head screws.Corrosion-Resistant Cadmium-Plated Steel—The finish creates a better barrier against rust than zinc plating for use in wet and outdoor environments.
