Abstract
In a shelving system, a columnar post, an outer plate, and a fastening device for fastening the outer plate removably to the columnar post. The fastening device includes a bolt having a threaded shank and a transverse head, which is integral with the threaded shank, and which includes a longer portion and a shorter portion, and fastener, which is threadable onto the threaded shank. The bolt is adapted to be sucessively inserted through an aperture in the outer plate, inserted through an aperture in a front wall of the columnar post, rotated about the threaded shank in a clockwise sense, and drawn outwardly until the longer portion of the transverse head bears against a curved corner where the front wall merges with a lateral flange of the columnar post, so as to prevent further rotation of the bolt in a clockwise sense. The longer portion of the transverse head is conformed to the curved corner so as to bear in surface-to-surface contact against the curved corner. The longer and shorter portions of the transverse head are adapted to bear against the margin of the aperture in the front wall, when the bolt is drawn outwardly, so as to prevent axial withdrawal of the bolt. The shorter…
