Abstract: A keybolt (40) includes a bolt member (10) and a key member (12). The key member includes a first leg (22) and a second leg (24) which are biased apart. The first leg includes steps (21) thereon. The key member is rotationally and slidably movable in a recess (20) on said bolt member. The key member is held in said recess by a rivet (14) which extends through elongated channels (42) in the leg members. The key member is movable between a locked position in which it extends generally traversely of the axis of the bolt member so as to hold the keybolt in an aperture through which it extends. The key member is movable to an unlocked position wherein it is rotatable to extend coaxially with the bolt member and wherein the keybolt may be readily installed or removed from appropriately sized apertures.
