A torque wrench is used to apply and measure a specific amount of rotational force on a fastener, controlling its tightness. The idea is to reach a precise torque so the joint provides the right clamping force—neither too loose (which can allow it to loosen) nor too tight (which can strip threads or break the bolt). The wrench signals when the set torque is reached, either with a click, a digital reading, or a visual indication. Remember, torque relates to the force turned by the wrench and the lever arm, and it’s influenced by friction and thread size, so following the specified torque values is essential. It does not measure length, color, or temperature.
