Cup flat washer is generally used to offer support, insulation, or a cosmetic finish to bolts or screws particularly those with countersunk heads. Cup washers are made of a variety of materials depending on the intended application. These include light weight metals such as steel or brass, insulating materials such as plastic and, in the case of faucet and pump washers, leather. Cup washers are either designed to be surface mounted or countersunk. They often include features such as decorative snap-on caps and electrical terminal cut-outs.
There is no reason to go searching for top quality cup washers when can supply these too.
