Internal Tooth Lockwashers

Internal Tooth Lockwashers are available in steel with a zinc, black oxide, black zinc or yellow zinc finish; and in 18-8 or 410 stainless steel. Twisted internal prongs allow these lockwashers to dig and lock into the adjacent material, while providing a finished look on the exposed outer diameter.
