A torque wrench is a tool used to apply a specific amount of torque to a fastener, such as a bolt or nut. It is important to use a torque wrench when tightening fasteners to ensure that they are not over-tightened or under-tightened. Over-tightening can damage the fastener or the workpiece, while under-tightening can lead to the fastener coming loose.
Torque wrenches come in a variety of types, including click-type, beam-type, and digital torque wrenches. Click-type torque wrenches are the most common type and work by making a clicking sound when the desired torque is reached. Beam-type torque wrenches use a beam to indicate the amount of torque being applied. Digital torque wrenches are the most accurate type and display the torque reading on a digital display.
