Abstract: A securing element includes a threaded region, wherein a securing rotational direction and an axial clamping direction are defined by the thread design. The securing element has a head with a head lower face which faces the clamping direction and via which a force-fitting connection with a component can be produced. The head is designed such that the head lower face has an edge region at a radial distance from the head center, and the contour of the head lower face runs opposite the clamping direction in the direction of the head center starting from the edge region, whereby a spring effect can be produced. The edge region has a changing circumferential level in the axial direction. Opposite the securing rotational direction, the circumferential level rises at a rising angle of maximally 15° in the clamping direction over a central angle of at least 65°.

Abstract: A connection element for an interlocking connection to at least one component includes at least one component held between the connection element and a securing element wherein the connection element and the securing element enter into a friction welded connection, having a head with a drive and a shaft having at least two cutting structures on a front side. The at least two cutting structures have cutting edges situated in a cutting plane, wherein the cutting plane borders the shaft, and the at least two cutting structures are also spaced apart in the circumferential direction and define a cutting diameter. A cross-section of the shaft has a reduced extension between the cutting structures relative to the cutting diameter, wherein the area of the reduced extension extends in the axial direction at least with the length of the cutting diameter from the cutting structures in the direction of the head.

Abstract: The invention relates to a screw having a head, an adjoining retaining section and a functional tip for use as a self-tapping screw. The functional tip is of greater hardness than the retaining section. The entire screw is made of hardened low-alloy carbon steel.

Abstract: The invention relates to a screw having a head, an adjoining retaining section and a functional tip for use as a self-tapping screw. The functional tip is of greater hardness than the retaining section. The entire screw is made of hardened low-alloy carbon steel. The special feature of this screw is that its functional tip has a higher carbon and/or nitrogen content than its retaining section.

Abstract: The invention relates to a worm shaft (10) comprising a first component (12) which bears a screw flight (14) and which has a first worm shaft end, and a second component (18) which has a second worm shaft end, wherein the axial extension (A) of the worm shaft (10) is defined by the spacing of the first worm shaft end from the second worm shaft end, wherein the axial extension (A) is fixed by connecting the first and second components (12, 18) at a predefined spacing by means of a connection member. The invention is characterized in that the axial extension (A) of the worm shaft (10) is set by the axial extension (A) of the connection member.

Abstract: The invention relates to a screw having a screw head (2), a screw shank (1) and a corrugated conical flange (4) which decreases in thickness toward the outside, which flange (4) will abut on a component part as the screw is being screwed into the latter. The two lateral surfaces (5, 6) of the flange (4) from the screw shank (1) to the outer edge (7) of the flange taper continuously toward the outside with the thickness of the flange (4) decreasing at the same time, with its corrugation (8) extending substantially over the entire radial width of the flange (4).

Abstract: The invention relates to a connection of a rotationally symmetrical steel fastening element to a flat aluminium component. The fastening element is provided with an electroplated aluminum coating and, at its end facing the component, forms a cone with a cone angle of at least ?=174°, wherein, through rotation and pressing against the component, said cone is superficially connected thereto by means of a friction-welding zone.

Abstract: A supporting sleeve configured for introduction into a penetration in a component. The hole of the supporting sleeve is penetrated by a fixing pin that is insertable into a carrier so as to fix the component on a carrier. The supporting sleeve includes a closed ring-shaped cross section and a plurality of axially and inwardly extending recesses extending over the entire length of the supporting sleeve and each of the recesses is formed by inwardly bent walls and a base connecting those walls, the walls being generally radially oriented and configured such that when radial pressure is applied to the supporting sleeve upon introduction into the penetration, each recess moves closer to each other.

Abstract: The invention relates to a flexible stop buffer, particularly for cover lids, with a buffer stem and a buffer head, said buffer head being axially displaceable and being slipped over the buffer stem, wherein disposed between buffer stem and buffer head in the interior space of the latter is a buffer spring, said buffer spring pressing the buffer head away from the buffer stem, and wherein the buffer head is secured by means of locking lugs against being pulled off the buffer stem. The buffer head is provided, inside an interior space surrounded by the locking lugs, with an axial projection, from which axial projection anti-rotation elements on the buffer stem are adapted to be brought into engagement with the buffer head.

Abstract: Supporting sleeve, said supporting sleeve being introducible into a penetration in a component, wherein, for the fixing of the component on a carrier, the hole of said supporting sleeve is penetrated by a fixing pin, particularly a screw, insertable into the carrier. The supporting sleeve is formed in cross section as a closed ring and comprises a plurality of axially extending recesses extending over the entire length of the supporting sleeve, wherein, when radial pressure is applied to the supporting sleeve, the walls of said recesses come closer to each other as the bases of the recesses bend in.

Abstract: Attachment device for a component to be attached to a plate, which is three-dimensionally adjustable with respect to the plate. The attachment includes a sleeve which is inserted into an opening of the plate and locked with respect to the plate by means of rotation. A tubular piece with a through hole is screwed into the sleeve into which a screw is inserted with substantial positive allowance for radial adjustability. This screw rests with its head at one end of the tubular piece and supports with its threaded part the component which abuts to the other end of tubular piece which, for axial adjustment, is optionally far screwed in.

Abstract: The invention relates to a securing device for a structural component to be secured to a panel with a tubular piece inserted into a penetration in the panel, into which tubular piece is inserted a screw, said screw being supported with its head on the one end of the tubular piece and holding the structural component with its threaded part, said structural component contacting the other end of the tubular piece, said tubular piece being screwed an optional distance into the penetration for axial adjustment. The tubular piece contains a distance detector, wherein, when the tubular piece is at a distance from the structural component, said distance detector is in its starting position projecting out of said tubular piece on its side facing away from the screw head and, when the tubular piece is in contact with the structural component, said distance detector is noticeably displaced out of the tubular piece.
