Abstract: A corrosion-resisting, self-tapping screw (1), in particular a concrete screw, to be driven into a bore, which has a wall, comprises a substantially cylindrical core (2) of corrosion-resisting metal with a central longitudinal axis (8); a thread (5), which is integral with the core (2); and at least one cutting element (9), which has at least one cutting head (12) for cutting engagement with the wall of the bore; the at least one cutting element (9) being inserted in the core (2), tightly joined thereto and consisting of a hardened metal, and the at least one cutting head (12) being arranged in the thread (5).

Abstract: A screw (1), in particular a concrete screw, for being screwed into a drilled hole (20) comprises a core (2) with a pilot end (3), a lengthwise screw-in direction (5) and a central longitudinal axis (4); and a thread (7), which is designed in a single piece with the core (2) and which comprises a cutting thread (9), the cutting thread (9) extending from the pilot end (3) counter to the lengthwise screw-in direction (5) and having flanks (12, 13), which are substantially parallel to each other, and cutting notches (17), which are open radially outwards; and a standard thread (11), which adjoins the cutting thread (9), with the standard thread (11) substantially having a triangular cross-sectional shape.
