Abstract
A method and an apparatus for the attachment to a component, for example a sheet metal part, of a fastener element comprising a head part and a tubular rivet section which is disposed concentric to an axis of symmetry of the fastener element and merges via a contact surface extending in a radial direction into the head part, wherein the rivet section is passed through the hole in the sheet metal part and the rivet section is beaded over, whereby the component is clamped in the region of the hole between the contact surface and the beaded over rivet section, are wherein the component is arranged above a riveting die button and the rivet section is pressed through the component and subsequently beaded over by the exertion of a local force on the head part of the fastener element, the local force moving in circles around the central axis of symmetry, or by exerting such a force on the die button, while simultaneously carrying out a relative axial feed movement between the tool exerting the force and the die button
