Abstract
In a pneumatic impact wrench there is an output shaft that is connectable in a removable manner to a screw coupling member; a torque sensor, which is mounted on the shaft, sends signals to a control unit that calculates the energy transferred through the output shaft and controls the wrench on the basis of a comparison between the calculated energy and a predefined threshold value.
