ABSTRACT:
A stud-like panel fastener with a wire-spring holdout for retaining the fastener in a retracted position on a panel. The fastener is formed with a bore extending from its leading end and a longitudinal slot at the lower portion of the fastener body in communication with the bore. A generally U-shaped wire spring member is carried within the bore with a lower protruding bearing surface on one leg of the member extending through the slot and beyond the periphery of the fastener body. When the fastener is retracted, the bearing surface of the spring member, in contact with the sidewall of the panel opening, holds the fastener against downward movement. Owing to the advantageous construction, the holdout is self-cleaning, as the sidewalls of the slot tend to wipe the bearing surface in use, and debris cannot build up behind the holdout and render it inoperative due to the large void behind the bearing surface. Also, the holdout can be quickly installed or replaced without special tools.
