A method facilitates assembling a gas turbine engine assembly including at least a first member and a second member. The method comprises inserting a threaded fastener through an opening formed in a flange, and providing at least one shank nut including a flanged mating end, an opposite non-mating end, and a body extending therebetween. The body includes an internal surface, an external surface, and a centerline extending between the body ends. The flanged mating end includes a substantially planar exterior surface that is aligned perpendicularly to the centerline and an annular groove that extends from the exterior surface at least partially towards the non-mating end. The method also comprises securing the assembly together such that the mating end is positioned flush against the flange and such that the threaded fastener extends at least partially into a bore extending through the shank nut and defined by the shank nut internal surface.

What is claimed is: 1. A shank nut for mating with a threaded mating component, said nut comprising: a flanged mating end comprising an exterior surface, said exterior surface is substantially planar; an opposite non-mating end; and a body extending therebetween, said body comprising an internal surface and an external surface, said body further comprising a centerline extending between said mating end and said non-mating end, and an unthreaded shank barrel extending outward from said mating end in a direction away from said non-mating end, said internal surface defining a bore extending between said mating end and said non-mating end, said bore sized to receive at least a portion of the mating component therein, said mating end exterior surface is perpendicular to said body centerline and comprises a groove extending at least partially circumferentially around said body bore, said groove extends axially from said mating end exterior surface at least partially towards said nut non-mating end and said groove is defined radially outward from said shank barrel, said body further comprises a hook extending outward from said body external surface, said hook is a distance from said mating end, said body further comprising a chamfer, said chamfer extends substantially planarly along a chord of said mating end wherein at least a portion of said shank nut body is chamfered adjacent said mating end and diametrically opposite said hook with respect to said centerline. 2. A shank nut in accordance with claim 1 wherein said mating end groove facilitates redistributing reaction loading radially outward from said body bore when said nut is coupled to the mating component. 3. A shank nut in accordance with claim 1 wherein said mating end groove facilitates reducing an amount of bolthole rolling when said nut is coupled to the mating component. 4. A shank nut in accordance with claim 1 wherein said mating end exterior surface facilitates substantially even clamping loading across said mating end when said nut is coupled to the mating component. 5. A shank nut in accordance with claim 1 wherein said hook is configured to prevent said nut from rotating after said nut is coupled to the mating component. 6. A shank nut in accordance with claim 1 further comprising a shank barrel extending outward from said mating end, said shank barrel is configured to retain said nut to the mating component during coupling of said nut to the mating component. 7. A coupling assembly for a gas turbine engine, said coupling assembly comprises: a flange comprising at least one fastener opening extending therethrough, said at least one fastener opening sized to receive at least a portion of a threaded fastener therethrough; and a shank nut for mating with the threaded fastener, said shank nut comprising a flanged mating end, an opposite non-mating end, and a body extending therebetween, said flanged mating end comprising a substantially planar exterior surface, said body comprising an internal surface and an external surface, said shank nut further comprises a hook extending outward from said body external surface, said hook is a distance from said mating end, said body further comprising a centerline extending between said mating end and said non-mating end, and an unthreaded shank barrel extending outward from said mating end in a direction away from said non-mating end, said internal surface defining a bore extending between said mating end and said non-mating end, said bore substantially concentrically aligned with respect to said body and sized to receive at least a portion of the threaded fastener therein, said mating end exterior surface is perpendicular to said body centerline and comprises an annular groove extending generally axially from said mating end exterior surface at least partially towards said shank nut non-mating end, said flange coupled against said shank nut mating end and said groove is defined radially outward from said shank barrel, said body further comprising a chamfer, said chamfer extends substantially planarly along a chord of said mating end wherein at least a portion of said shank nut body is chamfered adjacent said mating end and diametrically opposite said hook with respect to said centerline. 8. A coupling assembly in accordance with claim 7 wherein said shank nut annular groove is configured to distribute reaction loading radially outward from said nut body bore when said nut is coupled to said flange. 9. A coupling assembly in accordance with claim 7 wherein said shank nut annular groove facilitates reducing an amount of reaction loading induced to said flange by said shank nut when said shank nut is coupled to said flange by the threaded fastener. 10. A coupling assembly in accordance with claim 7 wherein said hook facilitates preventing rotation of said nut when said shank nut is coupled to said flange by the threaded fastener. 11. A coupling assembly in accordance with claim 7 wherein said shank barrel is configured to be inserted at least partially through said flange fastener opening for retaining said shank nut to said flange during coupling of said nut to said flange.
