Abstract
A captive panel fastener assembly for joining a panel to a sub-structure. The fastener assembly includes a sleeve bolt, a grommet assembly which is attached to the panel and a receptacle assembly which is attached to the sub-structure. The sleeve bolt passes through the grommet assembly and engages the receptacle assembly thereby joining the panel and the sub-structure. The bolt includes an enlarged head and a threaded shank with a pair of slots extending longitudinally along the outer periphery of the shank. A C-shaped ring is trapped in the grommet assembly and has a pair of inwardly extending ends riding in the slots. In this manner, when the grommet assembly is installed in an aperture in the panel, which may be the skin of an aircraft panel, the bolt can be pushed between positions whereby, in a first position, the grommet assembly and C-ring are at one end of the shank holding the head and shank outwardly from the aircraft panel and, in a second position, the C-ring rides along the slots and abuts against the head so that the remaining threaded shaft can extend through the aperture with a stud on the receptacle assembly threaded thereon securing the panel to the sub-structure…
