Abstract: A hollow element such as a hollow rivet or a nut element for attachment to a component consisting of a composite material such as a fiber reinforced plastic part or a fabric rein-forced plastic part is presented. The element has a flange part and a shaft part extending away from the flange part and/or a rivet section, wherein the rivet section, is present, can also be formed at the free end of the shaft part, with the a hollow element furthermore having a central passage, which is optionally provided with a thread cylinder. The hollow element is used in combination with an auxiliary tip which is either inserted from the flange side of the element through the passage, or from the side of the free end of the shaft part of the rivet section into the passage, such that a conically converging region of the auxiliary tip projects from the free end of the shaft part or of the rivet section.

Abstract: A method and an apparatus for the attachment of a fastener element to a component, for example a sheet metal part, wherein the fastener element is a nut element and has an axis of symmetry, a head part having a contact surface which enters into contact with the component, a threaded bore and also at least one undercut which receives the material of the component, and wherein the material of the component is pressed against the contact surface and into the undercut by means of a first tool having a die button shape matching the design of the nut element. A local force is exerted on the head part of the nut element or onto the tool to the side of the axis of symmetry and is moved circularly around the axis of symmetry while simultaneously carrying out a relative feed movement between the tool and the nut element between which the component is arranged in order to press the material of the component into the undercut.

Abstract: A component assembly comprising a sheet metal part and a nut element attached thereto, the nut element being arranged in an opening of the sheet metal part and being adapted to receive a bolt element having a shaft part with a thread and a head part of larger radial dimensions is wherein the sheet metal part has at least one hole adjacent to the nut element which is not covered over by the nut element but can be covered over by the head part of the screwed-in bolt element. A component assembly of this kind is in particular suitable for an oil pan since the oil can flow through the holes. A method is also claimed.
