Which tool would you use to tighten fasteners to a precise specification?

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

Answer: (A)

Tightening a fastener to a precise specification requires measuring and controlling the exact amount of twisting force applied. A torque wrench is designed for this: you set the desired torque, and the tool signals or stops when that value is reached, ensuring consistent, correct tension. This prevents under-tightening, which can loosen parts, and over-tightening, which can strip threads or break bolts. Other tools don’t provide reliable torque control. A hammer delivers impact, not a measurable torque. A screwdriver may apply rotation but does not regulate torque (unless it’s a specialized torque screwdriver). Pliers simply grip and twist without any torque measurement, leading to inconsistent results. That's why the torque wrench is the best choice here.
