摘要： In a screw (1) for mutual fastening of two components (2 and 3) there is provided a shank (4) with a thread (6), an unthreaded shank portion (7) and a screw head (5). The end region (8) of the thread (6) adjacent to the unthreaded shank portion (7) tapers with constant thread pitch (S), and so the tapering end region (8) of the thread (6) forms a kind of frustoconical envelope surface (10) upon rotation of the screw (1). During setting of the screw (1) and during over-torquing thereof, the end region (8) of the thread (6) acts as a kind of milling cutter and makes a frustoconical opening (13) in the component (3). The thread flights in the tapering end region (8) can then be braced against the wall of this opening (13), so that mutual contact pressure between the components (2 and 3) is possible despite over-torquing of the screw (1).

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).

摘要： A screw for fastening metal sections (10) onto a base (11), comprising a shank (2) with a threaded section (5) and an engaging section (3) enabling a screwin device to be arranged. The section of the shank which is connected to the engaging section (3) is designed as a cone extending in the direction of the engaging section (3). The thread engages into the base (11) whereby the metal section (10) is pressed against the base (11) when it meets the cone section (6). The turning moment can be substantially and appropriately increased by appropriate friction, so that the screw-in operation can be halted depending upon the turning moment.

摘要： A screw for securing sections on a substructure has a shaft (2) with a boring section (4) and a threaded section (5), as well as a screw head (3). The section (6) of the shaft (2) adjacent to the screw head (3) is conically tapered towards the screw head (3). The screw head (3) has bosses and/or recesses on its bottom side (7). When the screw is used to secure sections on a substructure, the section to be secured is pressed by the conical section (6) in the screwing direction against the fixed substructure (11).
