Claim 0:
1. An apparatus providing mating alignment between internal threading of a rivet nut and the external threading of the mandrel of an unclaimed rivet nut installation tool before anchoring the rivet nut in a hole in a substrate having a thickness, or the external threading of an unclaimed threaded fastener after anchoring in the substrate hole (collectively the “mating member”), the apparatus comprising:
(a) a rivet nut comprising an insertion portion having an external diameter sized for close insertion into the substrate hole and having an internal diameter having internal threading defining an essentially cylindrical mating chamber, and a trailing portion comprising a trailing end having an essentially circular opening having a circumference defined by an internal wall defining an essentially cylindrical cavity spanning at least the substrate thickness and leading to said mating chamber, the mating chamber having an internal diameter smaller than that of said opening and cavity; and
(b) a bushing sleeve having a maximum outer diameter sized for snug insertion and retention within said cavity and having an inner diameter sized to guide the external threading of the mating member into optimally aligned rotational mating with said internal threading of the mating chamber.
