Self positioning nut

A nut for applying a compressive force to one or more components mounted on a shaft to position the components against a fixed surface of said shaft, comprising:

• an annular portion having a plurality of threads on the inner diameter for securing said nut to said shaft;
• a centering member extending inward from said annular portion to contact said shaft and center said nut to said shaft;
• and
• a spring portion having a first axial end integral with said annular portion, a conical portion extending from said first axial end to a second axial end, said second axial end deflecting toward said annular portion upon application of said compressive force.

A gas turbine engine comprising:

• a shaft with a radial flange at one end and threads at the opposite end;
• a plurality of engine components concentric with said shaft and axially stacked on said shaft against said radial flange;
• and
• a nut for piloting said plurality of engine components to said shaft, said nut having an annular body having threads on its inner surface for mating with said shaft threads and a flat plate extending at an angle from said annular body to said engine components so that said annular body and said flat plate form an inverted V shape and define a circumferential channel therebetween.
