A front mounted retaining mechanism including a retention device and a captivatable device. The retention device has a head and a hollow shank. The head or the shank may include inwardly directed threads. The shank may include outwardly directed threads to facilitate mounting within a structure. The captivatable device includes a head and a shank, with the shank including a portion having a greater diameter than the remainder of the shank. That portion may be threads or a retainer ring. The captivatable device is threaded into the retention device in such a way as to allow its captivation therein. Then the first structure is aligned with a second structure into which the captivatable device is mounted.
