Hand tool and method for loosening of attachment means, such as a nut, bolt, screw or the like. The hand tool comprises three main parts, a support arm (1), a torque application arm (2) and a socket (3). The socket (3) is intended to grip into the bolt head and mediate a torque from the axle (6) of the hand tool. The support arm (1) forms a holding-up against a supporting base and the torque application arm (2) is used to apply a torque. Both the support arm (1) and the torque application arm (2) have latching devices with respect to the axle (6), which locks in the same direction and implies that a torque applied by the torque application arm (2) is maintained by action of the latching mechanism of the support arm (1). Furthermore, the hand tool is preferably designed with a torque enhancement (8).
