Abstract

The invention relates to a self-cutting screw (1) having a screw shank (2), a screw tip (3) an a pointed thread as screw thread (5). The invention proposes to provide the screw shank (2), in a short portion (L) adjoining the screw tip (3), with cutting edges (6) on a diameter of the screw shank (2) by means of helical and sawtooth-shaped grooves (7).
