The pin is of one-piece construction and comprises a flange, an externally threaded stem, and a post. The stem is externally threaded and projects from a first side of the flange. The post is of non-circular cross-section and longitudinally irregular profile and projects from a second side of the flange. The stem is adapted to be threaded into an anchor, and the post is adapted to be properly shaped and then receive a cast body. An overlay is releasably mountable upon the cast body by means of a removable screw.
