Abstract
A screwing tool having a torque-introduction part (2) with a cavity (4) in which a profile body (3) is inserted in a rotationally fixed manner, the profile body forming, by its section which projects out of the cavity (4), an operating end (1) for torque-transmitting insertion into a screwing-tool entry opening of a screw head, wherein the torque-introduction part (2) forms a polygonal section for inserting the screwing tool into a screwdriver mount or a bit holder, and the operating tip (1) is rotable, counter to a restoring force, in relation to the cavity-opening edge (4') as a result of the profile body (3) being secured in the cavity (4) such that it is capable of torsion, having a torsion section (16) formed as a torsion bar. The profile body (3), which is produced from a hardened steel, forms the torsion section (16), which is fitted, by a securing section (18), in the base (4'') of the cavity, the base being coordinated to polygonal section (17).
