Screw for torque-limited fastening

摘要

In a screw for fastening sections to a substructure, a shank (2) is provided with a boring portion (4) and a threaded portion (5) as well as a screw head (3). The portion (6) of the shank (2) adjacent to the screw head (3) flares conically toward the screw head (3). On its underside (7) the screw head (3) is provided with projections and/or depressions. During use for fastening sections to a substructure, the section to be fastened is pressed by the conical portion (6) in screwing direction against the fexed substructure (11).
