Abstract (en)
[origin: EP0512248A1] The invention relates to a screwing tool, especially a screwdriver (1) or a screwdriver insert, for polygon socket screws (8), having flank sections (12) shaped convexly in the circumferential direction; to optimise the transfer of force, it is proposed that the flank sections (12/12') are interrupted with respect to one another in the central region of each flank (11) by a non-convexly running intermediate section (13, 13'). <IMAGE>
