What is the purpose of a torque wrench?

The purpose of a torque wrench is to apply a specific torque to a fastener. This tool is designed to ensure that nuts and bolts are tightened to the required specifications, which is crucial in various mechanical and automotive applications. Applying the correct torque is essential for ensuring the integrity and safety of mechanical assemblies; too little torque can lead to loose connections, while too much can strip threads or damage components.

Using a torque wrench helps maintain the proper balance of tension across fasteners, preventing issues such as fatigue failure or uneven load distribution. It is a critical tool in ensuring that mechanical components are assembled to the manufacturer’s recommended specifications for optimal performance and reliability.
