A torque wrench is a tool used to apply a specific torque to a fastener, such as a bolt or cap screw, ensuring joints are tightened to a precise specification. It differs from a standard ratchet by providing controlled twisting force rather than a rough estimate.
Torque wrenches come in several designs: beam, click, dial, digital, and hydraulic (or pneumatic) torque wrenches
Units used include newton-metres (Nm) and pound-feet (lbf-ft). Common ranges: consumer models from 5 to 200 Nm;
How to use: select the required torque, attach to the fastener, ensure proper alignment, and apply force
Calibration and maintenance: torque wrenches should be calibrated periodically, with intervals depending on use, typically 1
Safety and notes: using incorrect torque can lead to fastener failure or joint damage. Always follow manufacturer
