ABSTRACT:
A panel fastener includes a smooth-surface cylindrical shroud encompassing the periphery of the screw head. The shroud is freely rotatable about the shank of the screw and has sides extending down around the barrel which is affixed to a panel. The shroud is fitted to the screw by an internal flange which is yieldably held between the underside of the screw head and the end of a spring. The top edge of the protective shroud does not extend above the head of the screw. The components are dimensioned so that the sides of the shroud are held away from the top side of the panel when the screw is fully compressed. The fastener may be press-fit into a panel as an assembled unit by applying ram pressure to the top of the screw assembly and barrel.
