Torque wrench

A torque wrench, also known as a "speaker" or "smart wrench", is a wrench with a built-in dynamometer, designed to tighten threaded connections with a certain effort. This tool is also called a torque wrench, this is due to the fact that it can be used to determine the tightening torque of the screw fastening and tighten the fasteners with the required force. Torque wrenches are designed for the normalized tightening of screw connections, most often this tool is used in car repairs, for example, for tightening spark plugs, when tightening wheel bolts, fastening the cylinder head and for other objects where it is recommended or required to take into account the tightening torque.
