Abstract

An article or an assembly comprising first and second structural members, and a plurality of offset stud fasteners securing the first and second structural members together. The first structural member preferably comprises a pair of spaced, channel-shaped uprights, each having a plurality of like-oriented, elongated openings therein, wherein each opening has a circular first or upper portion, a circular second or lower portion of smaller diameter than that of the first portion, and a keyway of restricted width connecting the first and second portions. The second structural member has therein a plurality of longitudinally extending openings, each having an upper portion and a lower portion which is larger than the upper portion. The assembly further comprises a plurality of offset stud fasteners, each having a circular head, a shank comprising a cylindrical first portion and an oblong neck portion of restricted width having spaced parallel flat sides and arcuate ends, and a base member of large size than said shank and projecting from an end of said shank which is opposite from the head. To secure the first and second structural members together, a plurality of offset stud fasteners are inserted into respective openings in the first structural member, the head of the fastener being inserted in any orientation into the larger portion of the opening in the first structural member, then rotated once to align the side surfaces of the neck of the fastener so as to pass through a middle portion of restricted width in said elongated opening, and then rotated a second time to locking position.
