The hand tool includes tree main parts, a support arm, a torque application arm and a socket. The socket is intended to grip into the bolt head and mediate a torque from the axle of the hand tool. The support arm forms a holding-up against a supporting base and the torque application arm is used to apply a torque. Both the support arm and the torque application arm have latching devices with respect to the axle, which locks in the same direction and implies that a torque applied by the torque application arm is maintained by action of the latching mechanism of the support arm. Furthermore, the hand tool is preferably designed with a torque enhancement. |
