A self-piercing rivet for connecting high-strength steels. The rivet having a head which has a head diameter (DH); a shank which has a shank diameter (DS); and, located at the foot end of the shank opposite the head, the shank has radially outward a flat surface section and radially inward an axial recess defining an axial depth (LB). The ratio of axial depth (LB) of the recess to the shank diameter (DS) is smaller than 0.3.

The invention relates to a connection comprising at least two components having the following features: a first component and a second component, of which at least the second component comprises reinforced plastic, a self-piercing connection element (30) having a head and a shaft, the head thereof being supported on the first component and the shaft thereof running completely through the first and the second component, and a disc-shaped counter bearing to which the shaft is fastened such that the at least two components are fastened between the head and the counter bearing. The invention further relates to a method for the production of said connection.

The present invention provides a fastener that serves as a replacement for joining a pair of metal sheets or similar materials. The fastener can be used to replace an original fastener that has worm a large hole into the sheets of material. The fastener provides a widened shaft to accommodate the widened hole while retaining a small head size comparable to that of the original fastener. In this way, the fastener of the present invention can be used in the widened hole while retaining the appearance of the original fastener.

A brake disc includes a friction ring having a first material and a brake rotor hat having a second material that is different from the first material. The friction ring includes a flange formed in the axial direction, and the flange is connected to an edge of the brake rotor hat oriented towards the friction ring, by means of at least one connection element designed as a rivet. The rivet head is in flat contact with the surface of the brake rotor hat facing away from the flange.

A module mount having at least one module that can be mounted on the module mount, wherein the module can be mounted on the module mount via at least one caulking element, such that the respective caulking element, which is composed of a thermoplastic, extends through a hole in a section of the respective module that can be mounted on the module mount made of a thermoplastic or thermoset, and is hot-caulked at an end projecting out of the hole, wherein at least one projection is formed on the section of the respective module that can be mounted on the module mount in the region of the respective hole of the section of the respective module that can be mounted on the module mount made of the thermoplastic or thermoset, which projection is engaged in a press fit with the hot-caulked end of the respective caulking element.

The present invention relates to headed push-in fasteners of the type produced by Penn Engineering & Manufacturing Corp. known as TackPins and TackScrews. More specifically it relates to a Tack Pin or a Tack Screw with a Belleville head that provides the functionality of a Bellville washer without needing a separate part. When installed, the compression of the Bellville shaped head will cause a permanent loading to be applied under the head of the fastener, essentially creating a clamping force to the members being attached.
