ABSTRACT:
A two-part panel fastener comprises a socket member and a stud member. The socket member includes a base, an elongated retaining head supported above one side of the base, a receptacle defining a central bore extending from the opposite side of the base, a lip which constricts the opening to the bore, and a frusto-conically shaped flange extending from the end of the receptacle and having a concave surface facing away from the base and surrounding the opening to the bore. The elongated retaining head is adapted to pass through an elongated or "double-D" shaped aperture in a first panel and to be retained relative to the first panel when the head is turned a quarter-turn. The stud member includes an upper shank with a plurality of circumferential ridges which interengage with the lip when the upper shank is inserted into the bore of the receptacle to permit the stud member and socket member to be removably joined together, a lower shank with a plurality of circumferential ridges which flex inwardly as the lower shank is pressed through an aperture in a second panel and which expand after they clear the aperture to hold the stud member relative to the second panel, and a relatively rigid collar between the lower and upper shanks which limits the travel of the lower shank into the second panel aperture.
