Which tool pair is used to cut or form threads on components?

• A. Hacksaws
• B. Drills
• C. Micrometer calipers
• D. Taps and Dies

Answer: (D)

Threading needs tools that actually cut the groove into the material. A tap creates internal threads inside a hole, while a die cuts external threads on the outside of a rod or bolt. Using them together (a taps and dies set) lets you form matching threads so fasteners can mate properly. Hacksaws cut through material with a serrated blade; drills bore holes but don’t form threads; micrometer calipers measure dimensions and don’t cut. So the tool pair that cuts or forms threads is taps and dies.
