Abstract: A fastening element (10) comprising a screw (1) with a screw head (11) and a sleeve-shaped rivet arrangement (2) through which the screw (1) passes. Starting from the screw head, the rivet arrangement (2) has an installation spacer region (21), a deformation region (22) and a drive region (23) into which the screw is screwed. Seen from the drive region (23) to the screw head, the circumferential boundaries of the drive region (23) lie within the boundaries of the deformation region (22), the boundaries of the installation spacer region (21) protrude radially over the boundaries of the deformation region (22), and the boundaries of the screw head protrude radially over the boundaries of the installation spacer region (21). The installation spacer region (21) and the deformation region (22) are designed in such a manner that, as the screw is tightened, first of all plastic deformation of the deformation region (22) occurs.

Abstract: In order to further develop a blind rivet element (5) comprising a head (51), an adjoining hollow shaft (53), the outer side of which has an outer diameter smaller than the head (51), and an internal thread (54) provided inside the shaft (53) and having an axial separation from the head (51), in such a way that when installed the blind rivet element (5) always forms a controlled deformation, in particular in the form of a bulge, at the same specifiable location, it is proposed that the shaft (53) is provided with a radially outwardly protruding adjustment contour (55) in the region of the head (51), that the shaft (53) has a curvature (57) formed in the radial direction and that said curvature (57) is arranged between the adjustment contour (55) and the internal thread (54).

Abstract: A fastener arrangement comprising a main body having a driving head, a central bore with an inner thread opening out into a front face of the driving head, and a collar, axially protruding from the front face of the driving head and being coaxially arranged to the inner thread. The fastener arrangement further comprises a spring element axially abutting against the front face of the driving head having a central through hole which is coaxially arranged to the inner thread of the driving head and a bearing element axially abutting against the spring element having a central through hole which is coaxially arranged to the inner thread of the driving head. The collar axially protrudes through the through hole of the spring element and into the through hole of the bearing element, and wherein the collar at its end facing away from the driving head, which end is positioned inside the through hole of the bearing element, provides a locking section radially extending outwardly.

Abstract: The disclosure refers to an insert for attaching a first component to a second component. The insert comprises a body with portions being arranged in the following sequence along a centre line of the insert between two front ends: A first portion with a first diameter; a second portion with a second diameter; a third portion with a third diameter, and a fourth portion with a fourth diameter. The geometries are such that the second diameter is less than the first diameter and less than the third diameter, and the third diameter is less than the first diameter. Finally, the fourth diameter is less than the third diameter.
