Rotationally symmetrical force-application means (12, 112) with, as viewed axially, a star-shaped outer contour or inner contour, preferably for connecting elements, wherein the individual arms (18, 118) of the star are designed as pointed arcs, of which the outer points lie on a common outer circle (22, 122), wherein an associated counterpart, in particular a bit, insert or screw head, has a mating contour which is adapted to the contour of the force-application means (12, 112) such that the radii (20, 120) of the flanks of the force-application means (12, 112) and the counterpart end up butting against one another in such a manner as to achieve a planar pressing surface; for the case where, in particular, the contour and mating contour corresponds to the shape of the force-application means according to the invention, the contour and mating contour are adapted by the radii (20) at the outer contour (12) being selected to be 4% to 12%, better 6% to 10%, better approximately 8% to 10%, smaller than the associated inner contour (112), while, in the case of the contour and mating contour, the inner circle (14; 114), on which the centerpoints of the radii (20; 120) are arranged around the axis of rotation (10; 110) of the force-application means (12; 112), has more or less the same diameter, in particular is greater by 4% to 6%, in particular by 5%, at the outer contour than the diameter at the inner contour. |
