Abstract:
Cold-rolled screw which has a head and a shank having an exterior surface with a thread and an end opposite the head with a guide for screwing the screw into a bore, wherein the guide includes a free end of the thread that is formed by an end surface which truncates the thread at the thread end, faces in the screw-in direction, and is directed obliquely with respect to a longitudinal axis of the screw so as to face generally away from the head, wherein the end surface is substantially flat and defined in part by a cutting edge that is an extension of a vertex of the thread and a base line which extends along the exterior surface of the shank between the cutting edge and a thread-base edge defined between one thread flank and the exterior surface of the shank, and wherein an extension of the base line away from the head runs at an angle relative to the thread-base edge which is substantially less than 90Â°.
