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).

摘要： The invention relates to a screwdriver adapter (1) which is provided with a receiving part (3) with an inner space (5). A nut (2) is arranged at the open end of the pot-shaped receiving part (3) in such a way that it is torsionally rigid and secured axially. A channel (8) joins with the contact part of the tool (6), said channel penetrating the nut (2) axially and leading to the inner space (5) of the receiving part (3). Sections of screw which break off in the contact part (6) when the screw is overturned pass through the channel (8) to the inner space (5) of the receiving part (3) where they collect until said space is emptied.

摘要： A lamina-shaped borepiece (4) for a self-boring fastening element (1) is provided at its front side with cutting edges (5, 6 ) flanked by grooves (7, 8) that extend approximately parallel thereto. Indents (9, 10) with set-back cutting edges (11, 12) are provided in the area of both front cutting edges (5, 6), so that a kind of stepped borer is created. The indents (9, 10) are formed in the area of the axial extension of the grooves (7, 8).

摘要： The invention concerns a screw (1) for the mutual securing of two components (2 and 3), a shank (4) with a thread (6), a non-threaded shank section (7) and a screw head (5) being provided. The end region (8) of the thread (6) facing the non-threaded shank portion (7) terminates with a constant thread pitch (S), the terminating end region (8) of the thread (6) forming a type of frustoconical envelope surface (10) as the screw (1) rotates. When the screw (1) is inserted and, if it is stripped, the end region (8) of the thread (6) acts like a milling cutter and produces a frustoconical opening (13) in the component (3). The thread turns can then be supported on the wall of this opening (13) in the terminating end region (8), such that, in spite of the screw (1) being stripped, the components (2 and 3) can still be pressed against each other.

摘要： The invention relates to a screw, comprising a shaft (2) and a head, said head being provided with a means (6) of engaging a tool. The shaft has a thread (4) and is provided with a boring part (5) at its free end. The height (LK) of the screw (1) head (3) measured in the direction of the screw axis is smaller than the lead (S) of the thread (4) formed on the shaft (2). A means (6) for engaging an external tool is configured on the head (3).

摘要： A hole-shaping and thread-forming screw (1) has a non-cutting hole-shaping end section (2) that ends in a point, a shaft section (4) provided with a thread and an engagement section (5) with a tool. The tapering end section (2) of the screw (1) has a flattened part (12) at least approximately parallel to the axis of the screw that extends over less than 180° and reduces the cross-section of the end section (2) over part of its length. This non-cutting hole-shaping screw may thus be driven much more easily into a workpiece.

摘要： Un élément d'assemblage par serrage (1) de type rivet borgne comprend une douille déformable (1), une tige (4) et une pièce de perçage (5). La pièce de perçage (5) est retenue de manière mobile ou amovible dans le sens axial (6) par rapport à l'extrémité libre de l'élément d'assemblage par serrage. Pendant la pose, la zone terminale libre (16) du manchon (2) coopère avec des surfaces d'appui (12) radialement saillantes de la pièce de perçage, de sorte qu'une force axiale est exercée sur ces surfaces d'appui (12) de la pièce de perçage (5). A mesure que la pose se poursuit, la pièce de perçage (5) est ainsi déplacée ou enlevée dans le sens axial, sous l'effet de cette force.
