Abstract

The pin (1) is counterbored (5, 7). The larger diameter is terminated internally in a truncated cone (8) and two diametral slots (4) are cut at right angles to each other, extending from the small bore end to just beyond this conical face. An expansion pin (2) slightly longer than the length of the small bore, has a head (11) of slightly smaller diameter than the large bore and a conical face (10) at the other end. The expansion pin diameter is intermediate between the bore diameters of the main pin and when inserted, forces apart the four "legs" formed by the slotted portion of the latter. In soft material the legs simply splay out, but in harder materials they deform radially, to give a good grip.
