A torque sensor, a music player and a circuit device are disposed in a main body of the hand tool. The circuit device includes a processing unit and a warning sound generator. An operation torque detected by the torque sensor is transmitted to the processing unit. In the case that the value of the operation torque is within a set range, the processing unit shuts off the warning sound generator and the music player can play music for a user to listen to. Once the operation torque of the hand tool becomes greater than the set torque value, the processing unit turns on the warning sound generator to emit a warning signal to alert the user. | 11-26-2009 |

The two polygonal holes are concentrically arranged to provide two fitting positions for fitting to threaded members. The first polygonal hole has multiple first internal angles each having two sides. A first small internal angle is further disposed on one side of each first internal angle of at least the first polygonal hole. The first small internal angles provide another fitting position for fitting to another size of threaded member. Accordingly, the wrenching tool is applicable to various sizes of threaded members. | 01-20-2011 |
