Disclosed is a sleeve screw comprising a sleeve, a position limiting member and a screw, wherein the sleeve includes a hollow tube and a locking element which is formed by extending from an entrance opening into an inner space of the hollow tube, the position limiting member is disposed within the hollow tube and is abutted against by a bottom of an extending end of the locking element. Thereby, when the screw is inserted into the sleeve, the position limiting member abuts against the screw to retain the screw in the sleeve and the locking element abuts against the position limiting member to fix the position limiting member in the sleeve.

A tolerance compensation arrangement for fastening first and second components with compensation of tolerances between the components. The arrangement comprises a base element having a first element with a first inner thread, a second element with a second inner thread, a supporting element arranged in between, and an adjustment unit with a threaded sleeve with an outer thread and a dragging unit at least partially arranged in the sleeve. The outer thread forms a first thread pairing of a first thread direction with the first inner thread. A fastening screw, can be screwed into the second inner thread via a second thread pairing of a second thread direction opposite to the first thread direction. The fastening screw can be connected to the adjustment unit via the dragging unit so that, during the rotation of the fastening screw, the adjustment unit co-rotates and is moved into abutment with the first component.

A tolerance compensation fastening apparatus (1) for fastening a first vehicle component (200) to a second vehicle component (300) by way of a bolt (100), the fastening apparatus being set up to compensate for a tolerance within a tolerance compensation range. A fastening system including such a fastening apparatus, as well as to a method for fastening a first vehicle component to a second vehicle component by way of a bolt.

The present application provides a nut fastener, comprising a mounting nut and an adjustment bolt. The mounting nut comprises retaining arms and a nut receiving passage. The adjustment bolt is configured to be at least partially received in the nut receiving passage and comprises a bolt receiving passage. A bushing is arranged in the bolt receiving passage of the adjustment bolt and over molded onto a side wall of the bolt receiving passage by means of two-shot injection molding. The nut fastener in the present application is easy to mount and use.

The invention relates to a method for installing a piece of home automation equipment, and to a system for adjustably attaching a piece of home automation equipment to a wall, comprising at least two supports (1), each one comprising a support shaft and a holding device, and at least two adjustable attaching elements. The adjustable attaching elements each comprise a supporting frame (2) and a mechanical connection element (3). The adjustable attaching elements also comprise a locking device.

A contact carrier includes a carrier body receiving a plurality of contacts and a fastening element fastening the carrier body to a carrier element. The fastening element includes a first clamping element connected to the carrier body, a second clamping element formed on the carrier body in a shiftable manner and opposite the first clamping element, and a locking device locking the second clamping element in a position relative to the first clamping element. A distance between the first clamping element and the second clamping element can be varied by a relative movement of the second clamping element in relation to the first clamping element. The first clamping element and the second clamping element, by the locking device, exert a clamping force onto the carrier element arranged between the first clamping element and the second clamping element to hold the carrier element.

The invention relates to an apparatus for the compensation of tolerances between components to be screwed to one another, comprising a hollow-cylindrical base element and a hollow-cylindrical compensation element which is in threaded engagement with the base element and which can be moved from a starting position into a compensation position by rotation relative to the base element. The apparatus is characterized in that a fixing means is provided by which the compensation element can be fixed in the compensation position relative to the base element.

A fastener assembly includes a stud, a threaded sleeve, and a compression spring. The stud includes a shaft with a first head at one end and a second head at an opposite end of the shaft, both heads with opposing bearing surfaces. The threaded sleeve is disposed about the shaft. The threaded sleeve includes external threads and a tubular interior with an inwardly projected shoulder. The compression spring is disposed about the shaft inside the threaded sleeve, with a first end bearing against a shoulder of the threaded sleeve and a second end bearing against a bearing surface of the second head. The spring urges the sleeve against the bearing surface of the first head. The assembly can maintain a preload between two components while allowing the components to be separated, and can also be used as a pressure limiter.

A tolerance compensating element for a device for connecting components by a connecting screw, includes an inner and an outer threaded part (10, 12), which are in threaded engagement with one another and, together, form a length-adjustable spacer (14), and a sleeve (30) which is held in the inner threaded part (10) and holds a spring element (34) in a position in which it comes into frictional contact with the circumference of the inserted connecting screw, and an unscrew protection device (44) in the form of a ring that is rotatably supported at one end of the spacer (14) and includes at least one arm (48) which projects axially into the sleeve (30) and, at the free end, forms an outwardly cranked claw (50) against which a stop (54) formed on the sleeve (30) abuts when a maximum unscrewing distance of the inner threaded part (10) is reached.
