Tab Washers are a mechanical locking washer that features one or more internal or external notches or tabs designed to hold the nut in place relative to the bolt or stud. The tab washer is installed between the bolt head/nut and the mating surface, and after the joint is tightened, the tabs are bent to engage in slots or keyways to provide a positive locking feature.
