Abstract: A tubular sleeve is provided, in particular for use as a force-absorbing sleeve. The sleeve includes a casing wall having a through-opening, wherein the sleeve is formed from plastic, and a modulus of elasticity of the plastic is between 15,000 MPa and 25,000 MPa.

Abstract: A modular screw is provided, wherein the screw includes, in an axial direction, the following elements: a screw head, a shank having a second functional portion, a third functional portion for distributing a prestressing force, wherein a washer is arranged in the second functional portion and is mounted so as to be rotatable about a longitudinal axis of the screw, and a fourth functional portion having an external thread, and wherein the washer is secured in an approximately positionally fixed manner in the axial direction by bearing against the second and the fourth functional portion.

Abstract: An insert threaded sleeve (1) includes a shank portion (2) extending substantially cylindrically along a sleeve axis (z) for insertion into a hole (32) or a bore; a disc portion (3) terminates the shank portion at an axial end and extends it outward at a right angle to the sleeve axis; a through-hole (5) extends along the sleeve axis through the disc portion and the shank portion for receiving a screw bolt; a component anti-rotation means (11) is configured on an outer surface (10) of the shank portion or on an underside of the disc portion facing toward the shank portion; and a screw anti-rotation structure (15) is configured on a surface (14) of the disc portion facing away from the shank portion. A connecting screw and a screw-sleeve combination are also provided.

Abstract: A system for fastening a first component with a through opening to a second component of a vehicle, including the first component and a fastening bolt, wherein a first delimiting sleeve with a first contact flange and a second delimiting sleeve with a second contact flange are provided, wherein the first delimiting sleeve and the second delimiting sleeve are insertable from opposite sides into the through opening of the first component and are connectable to each other by insertion of the first delimiting sleeve into the second delimiting sleeve such that the first contact flange and the second contact flange lie against the first component from opposite sides, wherein the fastening bolt is insertable through the delimiting sleeves into a fastening receptacle of the second component, and wherein the outer diameter of the second delimiting sleeve is smaller than the inner diameter of the through opening of the first component.

Abstract: A fastening system for fastening a component on a carrier component, comprising a fastening bolt, which can be fitted through a component through-passage opening and can be fastened in a fastening bore of the carrier component, and an outer sleeve and an inner sleeve, which is mounted in an axially movable manner in a through-passage opening of the outer sleeve, wherein the inner sleeve forms a through-passage opening for the fastening bolt, the fastening bolt mounted in an axially movable manner in said through-passage opening, a first spring washer, which can be fitted onto the outer sleeve and positions itself against a first side of the component, and a second spring washer, which can be fitted onto the outer sleeve and positions itself against a second side of the component, said second side being located opposite the first side.

Abstract: A threaded fastener (10) useful for fastening soft materials over an extended period of time includes a washer (16) having outwardly extending arms (46) received in axially extending channels (52) in an object (60) to be fastened, and a bolt (12) extending through the washer, the bolt having a head including a projection (26) engaging a locking feature (38,40) on the washer to resist relative rotation between the washer and the bolt in a fastened assembly.

Abstract: A device for pre-assembly of a pin-shaped device in a through-hole of a structural element, including a cylinder barrel-shaped sleeve, a plurality of first holding elements disposed at an inner side of the sleeve and projecting inwards, and second holding elements projecting outwards from both ends of the sleeve and being elastically deformable, such that upon insertion of the fastening device into the through-hole, the second holding elements can perform an evasive movement.

Abstract: A fastening means for pre-assembly of a pin-shaped joining means in a through-hole of a structural element comprising a cylinder barrel-shaped sleeve, a plurality of first holding elements disposed at the inner side of the sleeve and projecting inwards, and a plurality of third holding elements disposed at the outer side of the sleeve and projecting outwards, and second holding elements projecting outwards from both ends of the sleeve, that project farther outwards than the third holding elements, and that are elastically deformable, such that upon insertion of the fastening means into the through-hole, they perform an evasive movement.
