Tapping may be defined as cutting which type of thread?

• A. Internal thread
• B. External thread
• C. Left-hand thread
• D. Coarse thread

Answer: (A)

Tapping is the process of cutting internal threads inside a hole. When you drill a hole and use a tap to cut threads, you’re creating the female threads that a bolt or screw will thread into. This distinguishes tapping from cutting external threads on a rod, which uses a tool to create male threads on the outside. The direction of the thread or whether the pitch is coarse or fine isn’t what defines tapping; you can have right‑hand or left‑hand taps—and either coarse or fine pitches—depending on the application. The defining idea is that tapping produces internal threads to accept a fastener.
