Abstract: A low-profile fastener for securing parts such as swaybrace pads, mounting locks and suspension loops onto exterior surfaces of multiple ejector racks in aircraft. The fastener consists of a retainer housing formed with an annular neck and a thin wrench head, and an insert threaded into the nut with internal threads. The fastener neck is inserted from within the rack through a mounting hole aligned with a hole of the part to be secured. A bolt inserted through the holes from the exposed side of the part is screwed into the insert and tightened to the desired torque. The thin wrench head is the only portion of the fastener protruding into the rack.
