A torque wrench is specifically designed to apply a precise amount of torque to fasteners, ensuring that they are tightened to the manufacturer's specifications. This is crucial in many mechanical applications, as improperly tightened fasteners can lead to equipment failure, leaks, or structural weaknesses. The ability to set and measure the torque allows the technician to achieve the exact tightness needed, which is vital for maintaining the integrity of the assembly.

In contrast, measuring the length of bolts or tightening nuts exclusively does not capture the full functionality of a torque wrench. While a torque wrench can be used on nuts, its primary purpose is not limited to that alone; it serves a broader role in fastening operations that require precise torque application. Additionally, loosening screws is not an appropriate function for a torque wrench, as it is primarily intended for tightening rather than loosening.
