What is a torque wrench?

A torque wrench is a specialized tool used to apply a specific amount of torque to a fastener, such as a bolt or nut. It ensures that the fastener is tightened to the manufacturer's specifications, which is crucial for safety and performance in mechanical applications. Torque wrenches come in various types, including click, beam, and digital models, each providing a way to measure and control the torque applied. Proper use of a torque wrench helps prevent over-tightening or under-tightening, which can lead to equipment failure.
