Electrical Torque Wrench

A torque wrench is a tool used to tighten nuts and bolts to a predetermined torque value. This instrument allows fasteners to be tightened to the proper tension, helping avoid damage from over tightening or joints coming apart from under tightening.When you turn the handle of a torque wrench, the tool's overall length increases due to a spring or pneumatic air pressure meter inside. Your hands are connected to an internal mechanism that translates your energy into power. The torque wrench has a preset torque value that you can adjust by turning the dial.
