Abstract
The present invention provides a novel fastener member, stud, or other threaded member, for engagement with a female member, and the method of assembly thereof. The fastener member has a novel point which facilitates engagement of the fastener member in the threaded bore, greatly reduces the possibility of cross-threading and is especially suited for use in applications involving blind holes or the use of very thin threaded holes. The fastener member has a threaded shank portion. A point is provided at the end of the shank portion and includes an unthreaded radiused portion and a threaded transition portion between the shank portion and the radiused portion. The major diameters of the threads of the transition portion gradually lessen between the opposite ends thereof. The minor diameters of the threads of the transition portion gradually lessen between the opposite ends thereof. The radiused portion can be provided with a truncated end surface.
