This specification covers the acceptable material and dimensional requirements, and tolerances for bits of screwdrivers used for inserting and removing metal screws applied in surgical implants. The medical screwdrivers are available in the following types: Type I-single-slot bit; Type II-cruciate-slot bit; Type III-cross-slot (modified Phillips) bit; Type IV-hexagonal bit; Type V-square bit; Type VI-hexalobe bit. The bit and shaft portion should be fabricated from either martensitic stainless steel or cold worked cobalt-chromium-tung
