point at a work entering end thereof. The point includes a radiud portion which is engaged within the female member threaded bore to start engagement of the fastener member therewith. In certain embodiments, the point further includes an unthreaded portion, which has a diameter that is slightly less than a minor diameter of the shank portion, connecting the radiud portion and the threaded portion. The radiud portion has a maximum diameter which is slightly less than a minor diameter of the threaded bore. The radiud portion may take many forms and, for example, may be spherical; partially spherical; or formed from a predetermined number of radiud portions integrally formed with each other. To engage the fastener member and the female member, the radiud portion is dispod within the threaded bore and thereafter, rotational movement and an end load are applied to one or the other of the fastener member or the female member. The radiud portion is completely inrted into the bore prior to engagement of the shank portion with the threads in the bore, and will promote lateral as well as pivotal moment as required to align the respective members to attain proper thread engagement.国防大学录取分数线
