What is the purpose of a torque wrench?

• A. To apply a fastener to a precise specified torque value
• B. To measure torque values in a circuit
• C. To cut bolts to length
• D. To apply manual force without a torque setting

Answer: (A)

A torque wrench is used to tighten fasteners to a precise torque value. That precise setting ensures the fastener produces the intended clamping force—ne enough to hold components securely without risking thread stripping, bolt fatigue, or material damage from over-tightening, while avoiding loosening from under-tightening. Many torque wrenches signal when the preset torque is reached, so you stop exactly at the right point.

This tool isn’t meant for measuring torque in a circuit, cutting bolts to length, or applying force without a defined torque setting. Those tasks require different tools or methods.
