What tool is used to measure the turning force when tightening a fastener?

• A. Torque Wrench
• B. Caliper
• C. Hammer
• D. Pliers

Answer: (A)

Measuring the turning force applied to a fastener is about torque—the rotational force you apply to tighten or loosen something. A torque wrench is specifically built to apply a precise amount of torque and to tell you when you’ve reached the set value, usually with a click, beep, or digital readout. This helps ensure the fastener is tightened to the correct specification so the joint is secure without damaging threads or components. Other tools don’t measure torque: a caliper checks linear dimensions like diameter or thickness, not rotational force; a hammer delivers impact force and doesn’t provide torque measurements; pliers can grip and twist but don’t quantify the turning force or the final tightness.
