High-strength screw (), with a head () with a tool engagement contour (), a shank () with a free end () pointing away from the head (), a threaded section () with a thread () being arranged on the shank (), the thread () being formed as a metric ISO thread or inch thread, the head () and the shank () being de-signed as materially separate parts, the head () having a coupling recess () arranged radially inside with an axial force transmission element () and a torque transmission element (), the shank () having a coupling element () arranged radially outside on its outer circumference with an axial force transmission counter element () and a torque transmission counter element (), the coupling element () engaging in the coupling recess (), the axial force transmission element () and the axial force transmission counter element () being designed and arranged to positively interlock in such a way that an axial translatory movement of the head () relative to the shank () in the direction away from the free end () of the shank () is prevented or will be prevented, in particular non-releasably, and the torque transmission element () and the torque transmission counter element () being designed and arranged to interlock in such a way that a rotational movement of the head () relative to the shank () in the tightening direction of the thread () is or will be prevented.
