A hand tool includes an elongate body and a function end is connected on a first end and a handle is located on the other end of the body. A control device is connected on an outside of the body and includes a display screen which includes an illumination member. The control device is electrically connected with strain gauges so as to display the values of torques that the tool outputs from the function end. The illumination member can be a back light board or light emitting diode such that the users read the information in the display screen in dark areas.
