摘要： A screwdriver drive design for a screwdriver features an engagement end that is complementary to a fastening element drive design for a fastening element to be screwed. The fastening element drive design includes at least two drive surfaces formed on the fastening element for transmission of a torque suitable for rotation with a tool in a first rotation direction and transition surfaces disposed between these drive surfaces. The transition surfaces form a guide surface for the tool when rotating the tool in the first rotation direction and upon engagement of the tool in the other rotation direction causes an axial outward displacement of the tool, wherein the transition surfaces are formed as outside surfaces, and wherein the outside of the fastening element, outside the transition surfaces and the drive surfaces, lies in a cylindrical jacket forming a recess.
