A link for supporting a core engine within an outer shell of a gas turbine engine is described. The link, in one form, includes an elongate rod having a first end and a second end, and first and second rod end bearings are secured at the first second ends, respectively. Each end bearing includes a bearing head and a threaded stud extending from the head. The elongate rod includes a first threaded socket located at first rod end and sized to be engaged to the first rod end bearing stud, and a second threaded socket located at second rod end and sized to be engaged to the second rod end bearing stud. The first and second tapered jam nuts are located at the first and second ends of rod. Each tapered jam nut includes a nut end having, for example, a hexagonal head and a tapered portion extending from the nut end. A bore extends through each tapered jam nut, and the bore is sized to have the stud extend therethrough. The bore has internal threads at least at the location of nut end. Each socket includes a coaxial countersunk portion for receiving the tapered portion of respective jam nuts. As each jam nut is tightened in threaded engagement with one of the sockets, a clamping force is created between the socket, the jam nut, and the rod end bearing stud. In addition, the jam nut threads are be more highly stressed in the axial direction than the taper material in the radial direction. The threads are allowed to yield and redistribute the thread loads to adjacent threads without loosening the clamping load in tapered portion of the jam nut.
