摘要： A rolling tool (5) has a basic body (6) for fastening the rolling tool (5) in a rolling machine (1) and a profiled part (7) for the shaping treatment of a workpiece (2) to be rolled. The basic body (6) and the profiled part (7) are of multi-piece design. The basic body (6) and the profiled part (7), in their interconnected position, are mounted movably relative to one another in a plane perpendicular to the rolling direction (23). The basic body (6) of the rolling tool (5) can also be part of the rolling machine (1).

摘要： A high-strength screw (1) includes a head (2) and a threaded portion (5) including a thread (6) and a thread end (9) facing away from the head (2) in an axial direction. The threaded portion (5) includes an unhardened portion (12) starting at the thread end (9) and extending in an axial direction. The unhardened portion (12) has a hardness being reduced compared to an axial middle portion (11) of the threaded portion (5).
