A threaded fastener for preventing cross threading comprises a head, a cylindrical threaded shank projecting from the head, and a tip section formed on the end of the shank opposite the head. The tip section has a generally circular cross-section and has at least one and preferably two partial threads formed on it. The tip section may be generally cylindrical, conical, frusto-conical or bullet shaped. A method of manufacturing an anti cross thread fastener comprises forming a fastener blank with a shank portion joined to a tip section having a tip threading side and a reduced radius side, and applying threads thereto.
