Abstract
A self-retaining adjustable diameter bolt assembly including a bolt having a head, a shank, and a threaded end adapted to be inserted into aligned holes in a pair of abutting panels for subsequent coupling to a nut on the blind side of the panels. The bolt includes a pawl engaging one side of the panel in which the bolt is inserted with the head thereof on the opposite side of the panels. A plurality of bushing segments are mounted on the bolt shank, the pawl extending through an opening in the segment adjacent the threaded end of the bolt shank and retained therein by engagement with a slot through the segment while simultaneously being oriented in an operative position therein. A nut, having a skirt portion, is threaded onto the threaded end driving the segments forward and filling the spacing between the holes and the bolt shank. The skirt portion of the nut overlies the pawl and protects the same. The nut can be fully torqued to cause complete radial expansion of the bushing segments in the aligned panel holes before bottoming out against the panels.
