摘要:
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 has an axis of symmetry, a head part having a contact surface which enters into contact with the component, a fastening section having a thread 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 fastener element, are characterized in that a local force is exerted on the head part of the fastener 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 fastener element between which the component is arranged in order to press the material of the component into the undercut.
