This premium 4.5 mm cortex screw features a 72 mm thread length custom-machined from surgical stainless steel for rigid internal plate fixation across bone fractures. The precision self-tapping thread geometry cuts effortlessly into dense cortical walls, establishing an exceptionally tight mechanical interface with host bone blocks.
