Which of the following statements about tap wrenches is most accurate?

• A. Adjustable tap wrench
• B. Fixed-size tap wrench
• C. T-handle tap wrench
• D. Pliers

Answer: (A)

Tap wrenches are used to hold and rotate taps, transferring turning force to cut threads. Since taps come in many sizes, the tool must adapt to different diameters and keep the tap securely aligned. An adjustable tap wrench does exactly that by tightening a screw to clamp the tap shank, allowing a single tool to fit a range of sizes and turn smoothly without slipping. A fixed-size wrench would fit only one tap, which isn’t versatile enough for typical threading work. A T-handle describes the handle style, not the ability to adjust to different taps, and pliers can crush the square end, misalign the tap, and fail to provide the controlled torque needed. So the adjustable tap wrench is the best, most practical choice.
