The compression nut is used with a 3-deg Morse-type taper in the midstem junction to assure locking of the proximal body to the distal stem component. Application of the compression nut enhances the security of the connection by engaging the threads on the distal stem. The compression nut is machined to a smooth surface from Tivanium Alloy and Ti-Nidium hardened.
