Abstract
This invention provides a shear resistant panel fastener that includes a bolt having a head and a shank with a first relatively large diameter portion adjacent the head and a second smaller diameter threaded portion, a sleeve on the second portion of the shank, a collar around the sleeve and movable to a position around the first portion of the shank, the collar including a means for attachment to a workpiece, and a retainer means for prohibiting movement of the collar off of the sleeve in one direction. The smaller outer end of the shank is adapted to enter a clearance opening in a part for engagement with a floating nut at the opposite end of the opening, while the larger portion of the shank is drawn into the opening and the fastener is tightened. The smaller portion of the shank permits the fastener to be mated when the openings are misaligned while the larger portion of the shank provides shear resistance when the fastener is mated. An enlarged end thread portion retains the sleeve on the shank and fits in an internal groove in the sleeve to hold the bolt in its retracted position.
