A connector that receives a threaded apparatus and reduces stresses induced from the treaded apparatus into the connector is described. The connector includes a top side, a bottom side, and an opening that extends therethrough. The opening is defined by an inner surface that includes a threadform including a plurality of threads. The threads extend radially outward from the inner surface into the connector opening and include a first thread portion and a cutback that extends through a portion of the threadform. The cutback facilitates less stresses being induced into the first thread portion.

1. A method for fabricating a connector for a gas turbine engine, the connector sized to receive a threaded apparatus, the connector including a first side, a second side, and an opening extending therebetween and defined by an inner surface, said method comprising the steps of: forming threads into the connector inner surface, such that the threads are axially-spaced substantially constant along the connector inner surface and wherein a first thread is the first of said threads which initially engages the threaded apparatus that is rotated within the connector opening and coupled to said connector; and forming a cutback to extend into the connector inner surface to reduce stresses induced into the plurality of threads by the threaded apparatus wherein the cutback extends through the first thread. 2. A method in accordance with claim 1 wherein the connector opening has a center axis of symmetry extending between the connector top and bottom sides, each of the threads includes a root and a crest, said step of extending the cutback further comprises the step of extending the cutback through the first thread portion crest. 3. A method in accordance with claim 2 wherein the connector cutback includes a first end, and a second end between the first thread portion and the connector second side, said step of extending the cutback further comprises the step of extending the cutback obliquely through the first thread portion with respect to the connector opening center axis of symmetry. 4. A method in accordance with claim 3 wherein said step of extending the cutback obliquely further comprises the step of extending the cutback through the first thread portion such that the cutback first end is a first distance from the connector opening center axis of symmetry that is longer than a second distance that the cutback second end is located relative to the same center axis of symmetry.
