Which tool is specifically designed to tighten fasteners to a specific torque value?

A tool that is specifically designed to tighten fasteners to a specific torque value is the torque wrench. This instrument is essential in automotive work and applications where precise measurement of torque is crucial.

The torque wrench enables technicians to apply a preset amount of torque to fasteners, such as bolts and nuts, ensuring that they are neither too loose nor too tight. This level of accuracy is important to prevent damage to components or failure of joints, particularly in critical systems like the engine or suspension.

Unlike other tools mentioned, such as a socket wrench which can apply torque but lacks the ability to measure it accurately, a torque wrench allows for calibration to a specific value. This makes it indispensable for ensuring safety and performance in automotive repairs and assembly.
