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 includes 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 in a groove adjacent the nose of the bolt stops the downward movement of the retainer. A cup member surrounds the retainer thereby protecting the retainer during its movement along the grooves.
