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 is important to set the torque wrench correctly in order to ensure that the fastener is tightened to the proper specifications. Over-tightening or under-tightening a fastener can lead to a variety of problems, including damage to the fastener or the surrounding components.
There are two main types of torque wrenches: click-type and beam-type. Click-type torque wrenches produce an audible click when the desired torque is reached. Beam-type torque wrenches have a scale that indicates the amount of torque being applied.
