Abstract

See full text

A method for the attachment of a bolt element to a component is described. The bolt element has a head part having a contact surface and a shaft part extending away from the head part, the shaft part having a tip provided at its end remote from the head part, the tip merging into a thread cylinder, optionally via a cylindrical region. The bolt element is pressed with the tip to the fore against the component and the tip is pressed through the component until the side of the component adjacent the head part of the bolt element enters to contact the thread cylinder and the tip thereby generates a hole in the component. The bolt element is subsequently turned so that the thread of the thread cylinder forms an internal thread in the wall of the hole. A bolt element is also claimed.
