ABSTRACT:
A threaded insert for providing stronger threads to a parent material. The threaded insert includes a bushing portion having male threads on the external surface and female threads within an internal bore. The threaded insert also includes keys which lock the threaded insert into a threaded hole within the parent material. The keys are positioned within slots along the external surface of the bushing portion of the threaded insert. The slots include two substantially parallel walls which are substantially perpendicular to a bottom surface of the slots. A method for assembling the threaded insert reduces the tendency of the keys to be installed offset from the bottom surface of the slots.
