1. A method of manufacturing a single-piece fastener nut and sleeve structure, the method comprising:
providing a selectively hardened material blank having a nut portion having greater hardness than remaining portions of the material blank;
boring the material blank and internally threading the nut portion; and
machining a sleeve portion within a section of the remaining portions of the material blank, wherein the machining forms: (i) a bulbing portion positioned between a terminal end of the material blank and the nut portion, and (ii) a conical transition portion, positioned proximate to the bulbing portion, and having a vertex angle of between 10 and 25 degrees; and
wherein the bulbing portion is constructed and arranged to bulb outwardly and form a load bearing flange when the bulbing portion is compressed between the end portion and the nut portion.
