ABSTRACT:
A fastener assembly for joining a panel to a sub-panel comprising a receptacle assembly having a threaded stud secured to the undersurface of the sub-panel. The assembly includes a bolt having an enlarged head at one end and a nose at the other end. The panel has a countersunk opening aligned with an opening in the sub-panel. The bolt is threaded for threaded engagement to the stud. The body of the bolt has a plurality of spaced grooves extending longitudinally along the outer surface of the bolt body. A retainer surrounds the bolt body having spaced ears riding in the grooves and a stop ring in a groove adjacent the nose of the bolt stops the downward movement of the retainer. In this manner, the bolt may be disposed in the countersunk opening in the panel with the retainer on the blind side of the panel and the stop ring preventing movement of the retainer off of the bolt body thus retaining the bolt to the panel.
