发明名称 Captive panel fastener
摘要 A captive panel fastener includes a head, a shank and a threaded outer end, with slots extending longitudinally down through the threads towad the outer end of the fastener. A relatively rigid and inflexible retention washer is provided and this washer has inwardly extending prongs which fit into the longitudinally extending slots on the fastener. The outer end of the fastener has a hole in it, and, after the washer is in place, a forming tool is employed to deform the outer end wall of the opening, so that the wall is pushed outwardly to block the outer ends of the longitudinally extending slots, thereby holding the washer onto the fastener, and retaining it extending through a hole in a panel or the like through which it may have been inserted. A small washer may be employed at the end of the fastener between the ends of the slots and the deformed extreme outer end of the fastener.
