CA 2135743

A washer assembly combination for use with a threaded fastener which combination includes a rigid cup and a resilient member received within the cup. The resilient member, typically a polymer of ethylene propylene diene monomer, is oversized with respect to the cup interior such that, in use, the member is compressed so as to exert a compressive force on materials held together by the fastener. The assembly is useful for fastening together of sheet metal materials, and particularly, provides a system for sealing against the ingress of water between two layers of material in which such an assembled combination is used in conjunction with a clamping member.
