The torque-setting device (30) includes a knob inserted in the handle (13) and a pin (32) movable in and along the slot (14) as the knob is spun. The torque-measuring device (50) includes a measurement sleeve (60) and a collar (80). The measurement sleeve (60) is rotationally located around the shank (11) and includes a helical groove (61) defined in an internal side and a scale provided on an external side. A portion of the pin (32) is movably inserted in the helical groove (61) so that the measurement sleeve (60) is spun as the pin (32) is moved in and along the slot (14).
