摘要

The system is for fixture and release of screws and comprises a tool with a torque transmission component with a corresponding screw-side accommodation for the torque transmission component. The tool has a holding component for the screw head (3) with at least one securing hook (11). The corresponding screw (2) at the screw head has at least one back-cut, into which the securing hook of the holding component is pivotable by a rotary movement of the screw and/or the holding device, after the screw head has been set in the holding device. The back-cut is formed as a radial groove (13,14) which is circular-segment-shaped around the screw head. The depth of the groove is between a maximum value in the groove center and a minimum value at the groove ends.
