Abstract
A captive panel fastener having an enlarged head and a threaded shank with a pair of slots extending longitudinally along the outer periphery of said shank through the threads thereon. A C-shaped ring is trapped in a 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, such as in the skin of an aircraft panel, the fastener 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 and a nut threaded thereon securing the fastener to the panel.
