Zinc-Plated Steel External-Tooth Lock Washers
Manufacturer part: 97985A113
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.External Tooth—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.Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.
