Which device is used to ensure a fastener is tightened to a specified torque?

Setting a fastener to a specific torque is about controlling the clamping force so the joint is secure without risking damage. A torque wrench lets you preset the exact torque value and will alert you—usually with a click, a break, or a digital readout—when that target is reached. This precise control ensures the fastener is neither under-tightened nor over-tightened, which helps prevent loose joints or thread stripping and can extend the life of components. Other tools don’t provide torque control: a caliper measures dimensions, not force; a file removes material to shape parts, not tighten bolts; a hammer delivers impact force with no control over the final torque.
