What tool is used to measure the amount of torque?

The tool specifically used to measure the amount of torque is a torque wrench. This instrument is designed to apply a precise amount of torque to a fastener, such as a bolt or nut, ensuring that it is tightened to the correct specifications. Torque wrenches come in various types, including click-type and beam-type, but their primary function remains consistent: to provide an accurate measurement of torque during fastening tasks.

While other options listed may relate to torque in various contexts (like torque gauges or torque meters), they are generally more specialized instruments for measuring or indicating torque rather than tools specifically designed for applying a set torque during assembly. Torque wrenches are widely used in automotive, construction, and manufacturing settings due to their critical role in ensuring mechanical components are secured appropriately without over-tightening or under-tightening.
