Abstract
A captive fastener is disclosed having a longitudinal slot along the shank for receiving a hold out clip, and a pair of diametrically opposed slots for receiving a pair of push out clips. The push out clips are formed with hook shaped ends that catch and engage an edge of a wall surface to set the distance of depth of the fastener inside the wall. The hold out clip and push out clips are shaped to receded inside their respective slots in the presence of an interfering surface as the fastener passes through the wall in a first direction (insertion), but the push out clips will not recede into their slots in the second direction (withdrawal).
