ABSTRACT:
A pin fastening device having a double tapered head, the angle of one taper being on the order of 80.degree., or sufficient to withstand severe longitudinal forces, and the angle of the other taper being on the order of 10.degree., so as to provide a substantial interference fit between the pin and the work members. This double tapered head may be effectively utilized with a wide variety of pin fastener attachment end styles. Furthermore, an attachment end of a pin fastener is disclosed which includes a novel configuration of annular rings, which rings have a thread angle of 60.degree., and relatively small radii of curvature at their trough and peak. By having such a set of annular rings, one portion of the pin may be longitudinally extended sufficiently to give the pin large shear force resistance, while sufficient total ring surface is retained to withstand large tension forces. A single pin may thus have both a high shear and tension resisting capacity.
