The invention relates to a corrosion-resistant, threading (1), especially concrete screw, for screwing into a bore-hole with a bore-hole-wall, comprising an essentially cylindrical core (2) consisting of corrosion-resistant metal, with a central longitudinal axis (8), a thread (5) which is configured as a single piece with the core (2), and at least one cutting element (9) with at least one cutting head (12) for cutting into and hereby engaging with the bore-hole. The at least one cutting element (9) is introduced into the core (2) and permanently connected to said core and consists of a hardened metal. The at least one cutting head (12) is situated in the thread (5).
