Abstract
A screwing tool, including an elongate handle which, at each of the two ends thereof, bears a head pivotable about a pivot axis and having two torque transmission flanks in each case and has a force application flank for introducing a force in order to produce a torque on the head remote from the relevant force application flank, wherein, in a pivoting end position of the head, in which a stop of the head lies against a counter stop of the handle, a narrow side of the head functionally directed away from the stop forms an extension of the force application flank. The second head forms an extension of the force application flank and can be used as a hand grip.
