Abstract
A panel fastener includes a screw that is captivated to a ferrule and urged toward a retracted position by a spring which operates between the screw head and the ferrule. When the screw is in the retracted position, a collar of enlarged diameter on the screw occupies the area adjacent an internal annular captivation ring of the ferrule. The screw includes a flange that bears directly against the captivation ring providing a stop to prevent removal of the screw. The spring is preferably a coil spring that is operative against an outer flange of the ferrule.
