A fastener arrangement includes a threaded member having threads extending from a first end to a second end. The threads have a thread contour provided by a load and clearance flank surfaces joined to one another by a crest and root. For the external threaded member the crest provides a crest diameter, and a root provides a root diameter and is arranged between adjoining threads. At least one thread near the first end has a weakened thread contour that decreases rigidity of the one thread compared to other threads, enabling axial loads to be distributed more evenly between the threads.

Systems and methods for reducing friction during gas turbine engine assembly may comprise, a rear hub which may comprise a conical web, a horizontal arm coupled to the conical web, and/or a hub kickstand coupled to the conical web. The conical web, horizontal arm, and/or hub kickstand may converge at a pivot point. The hub kickstand may be removably coupled to the tie shaft.

A fastener arrangement has first and second threaded members. The fastener arrangement includes the first threaded member having threads that extend from a first end to a second end. The threads have a thread contour that is provided by load and clearance flank surfaces that are joined to one another by crests and roots. The crest provides a crest diameter. A root provides a root diameter and is arranged between adjoining threads. At least one thread near the first end has a weakened thread contour that decreases rigidity of the one thread compared to other threads. The threads extend along an axis. The crest diameter of the second threaded member varies and lies along crest angle relative to the axis and comprises a second threaded member that has load flank surfaces that are engaging the load flank surfaces of the first threaded member at thread contact interfaces. The thread contact interfaces are smaller towards the second end than thread contact interfaces toward the first end.
