Abstract

See full text

A fastener, particularly adapted to retain a screw, comprises a sheet metal body member. A double-sided adhesive tape may be adhered to one face of the metal member. The metal member is a unitary member having a top flexible leaf portion with a screw impression to receive and retain a screw, a 'U' shaped connecting portion, a bottom plate portion having a clearance hole to guide the screw, and a cone-shaped ring-like raised portion around the clearance hole. The cone portion may telescope into the screw impression dome to reinforce the dome. Three tabs project from the bottom face of the bottom leaf and project through the tape.
