More Information
Summary:An assembly comprising first (30) and second (32) structural elements having aligned holes, a fastener (34) that occupies at least respective portions of the holes without a surrounding sleeve, and a mating part (36) that is coupled to the fastener (34). The fastener (34) comprises: a head (38); a circular cylindrical shank (6) extending from the head (38); a mating portion (8) comprising external projections; and a transition portion (10) disposed between the shank (6) and the mating portion (8). The transition portion (10) comprises a tapered lead-in section that meets the shank (6) at a shank/lead-in intersection and a radiused lead-in section that meets the tapered lead-in section. The tapered lead-in section tapers gradually in a first axial direction toward the mating portion (8) and has a first profile that is linear and a taper angle equal to or less than 20 degrees, while the radiused lead-in section curves abruptly in the first axial direction and has a second profile that is a circular arc having a radius.
