ABSTRACT:
A nut plate fastener retains a screw inserted through an aperture formed in a panel. A double-sided adhesive tape may be adhered to one face of the fastener to mount in the panel aperture. The nut plate fastener consists of an integral member and includes a bottom plate with a cone-shaped ring-liked raised screw impression to receive and retain a screw, and a top plate portion connected to the bottom plate. The screw when in the fastened position is confined between the top and bottom plates as to be isolated from objects contained within the panel and adjacent the nut plate fastener. Three tabs project from the bottom face of the bottom plate and project through the tape which centers the fastener in the panel aperture.
