ABSTRACT:
A nut plate fastener, particularly adapted to retain a screw and to seal a hole in a panel having foamed-in-place insulation, comprises a sheet metal body member and a double-sided adhesive tape adhered to one face of the metal member. The metal member is a unitary member having a top leaf with a screw impression to receive and retain a screw, a "U" shaped connecting portion, and a bottom leaf having a clearance hole to guide the screw. As a safety feature, when there is high torque on the screw, a ring-like raised portion around the clearance hole 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.
