ABSTRACT:
A three element fastening assemblage comprising a nut formed with a head end and a collared end, a dished-shaped washer and a retaining strap having a circular aperture aligned on the strap longitudinal axis of symmetry. The washer central base has its seating surface axially depressed from a radially extending peripheral washer flange facing surface. The retainer strap has oppositely extending bifurcated ends defining pairs of washer retention prongs the distal ends of which are pre-bent to extend normally from a facing surface of the strap. The nut is initially positioned with its head end extending through the strap aperture with the nut collar providing a stop shoulder contacting the strap facing surface. With the strap facing surface in flush contact with the washer facing surface the prong distal ends are reverse bent about the washer flange circular edge thereby capturing the nut collar between the strap facing surface and the washer seating surface. The assemblage enables rotation of the nut relative to the strap and washer about the strap principal axis.
