Abstract: A device for processing a belt strap for storing screws, in which the belt strap has a flat, U-shaped cross section that has a periphery that has a ratio of no more than 11:10 relative to the non-flanged belt. A guide device for the belt strap guides and holds the belt strap. The screws can be pressed out from the upper side of the belt strap. The guide device (3) has two guide slits (10) receiving the belt strap (2) in at least the region of the flanges (4), each slit being L-shaped in cross section and each having a contact surface (5) for the underside (6) of the belt (20) and a guide rib (11) extending across the flange (4).

Abstract: A screw (60) is provided, having a shaft (32) and a head (66), for fastening a component onto a substructure utilizing a tightly pressing conical sealing disk (50) against the component. The screw head (66) is configured at the bottom (64) thereof around the shaft (32) as a cone that is tapered in the direction of the top (68) of the screw head (66). The cone angle of the conical sealing disk (50) measured against a perpendicular line to the disk axis is equal to, or larger than the cone angle (alpha) of the screw head (66), which is measured against a perpendicular line to the screw axis. When the screw (60) is tightened, the conical bottom (64) of the screw head (66) and the conical top (58) of the sealing disk (50) are in mutual surface contact with each other. This maintains a sealing connection. Through the conical configuration of the bottom (64) of the screw head (66) the so-called “cupping” of the sealing disk (50) is prevented when the screw (60) is tightened.

Abstract: A screw (1) having a head (2), a shaft (4) that includes a thread (5), and an interior engaging member (3) in the head is provided. The screw (1) is produced from an ultra-high strength steel using a cold forming method.

Abstract: A threaded element (1) is provided having at least two slots (3), notches, grooves or the like that intersect the thread (2). The slots (3), notches, grooves or the like are configured in relation to the thread (2) so that they intersect the thread (2) to form a sharp cutting edge on the thread flanks (4), thus preventing reverse rotation. The slots, notches or grooves have no more than 25-times the pitch and the same rotational direction as the thread.

Abstract: A washer (14) and a threaded assembly (22) between a screw (30) and a workpiece (42) are provided. The washer (14) is offset up to an angle (?) with respect to a flat initial state, such that the washer has an insert thickness (De) that is substantially greater than the initial thickness (Da) thereof. The washer (14) is made of a malleable material. The length (Lg) of an unthreaded shank section (40) of the screw (30) is smaller than the sum of the thickness (Dw) of the workpiece (42) and the insert thickness (De) of the washer (14), and essentially not smaller than the sum of the thickness (Dw) of the workpiece (14) and the insert thickness (Da) of the washer (14). When the last thread of the screw (30) leaves the workpiece (42) on being screwed in, the force previously exerted on the washer (14) by the feed of the screw is zero.

Abstract: Detachable locking arrangement that includes a push-in element, a receiving member having an insertion opening structured and arranged to receive therein the push-in element and a locking device which is insertable into a clearance area of the receiving member. The clearance area is defined by a space arranged between the push-in element and an inner surface of the receiving member when the push-in element is inserted in the insertion opening. The locking device prevents removal of the push-in element from the receiving member when the push-in element is inserted within the insertion opening and when the locking device is inserted into the clearance area, thereby defining a locked position. The locking device is structured and arranged to automatically and releasably lock with the receiving member.

Abstract: A self-tapping screw having a boring part and a threaded shaft for fixing a panel-type object to a preferably metallic substructure is provided. The screw is configured in such a way that it produces a through hole in the panel type object, said hole accommodating the shaft with a degree of play and so that it produces a bore in the substructure into which the thread on the shaft cuts a counter-thread. The boring part includes a boring tip that is located eccentrically in relation to the longitudinal axis of the screw. The tip centers the screw during the positioning operation in such a way that the boring part executes a circular displacement about the boring tip, which expands the through hole to the desired size, whereas the bore in the substructure is produced with the diameter of the boring part.

Abstract: A stamped rivet (10) for the connection of metal sheets (12, 14) to each other is provided, and includes a shaft (16) with several circumferential ribs (18) located one above another on the shaft (16), a shaft end (20) for pressing through the sheets (12, 14) for connection to each other, and a head (26). An adjacent region (30) to the shaft end (20) has no circumferential ribs and has a diameter smaller than an outside diameter (D) of the circumferential ribs. The stamped rivet (10) is easy to set as the setting device only has to be able to push the stamped rivet (10) through the sheets (12, 14) for connection. Sheet material is then forced by plastic deformation into the circumferential grooves (38) formed between the circumferential ribs (18).

Abstract: A device for installing a stamped rivet into sheet metal is provided having an upper socket in which a stamp can be displaced, a fixed lower socket which is located at a distance from the upper socket and which receives the shaft of the stamped rivet during the stamping-in process, and which also includes a clamping bushing which is elastically pre-tensioned and surrounds the lower socket and protrudes above the lower socket in a direction of the stamp and acts as a support for the sheet metal which is to be joined by or with the stamped rivet. The stamp, lower socket and clamping bushing are configured so that when the rivet is stamped in, a peripheral groove formed in the rivet shaft directly below the head is filled with metal sheet material which is stamped through by the rivet during the fixing process and is initially formed downwardly and then plastically deformed into the groove.

Abstract: A method of manufacturing filling strips for placement between a surface and a corrugated member wherein the corrugation defines a profile. The method includes: providing a sheet of material having a longitudinal axis and first and second major surfaces; forming at least one cut generally through the sheet, the at least one cut extending generally in a longitudinal direction of the sheet to follow a path that corresponds to the profile, wherein the at least one cut divides this sheet into at least two filling strips each having a corrugated member contacting surface that extends between the first and second major surfaces; and separating the sheet into the at least two filling strips.

Abstract: A wooden beam (1) has several sections which are subjected to a transversal tension and which affect in particular the areas in which there are recesses or openings (3). Rod-shaped elements are provided in the form of screws (4) which are introduced in such a way that they extend crosswise to the longitudinal direction of the beam (1) in order to absorb this transversal tension. These screws are screwed in from the top side (5) or the underside (6) of the beam (1) and each extend over part of the height (H) of the beam (1) only and are therefore directly associated with the area (2) that is subjected to transversal tension.
