Abstract
Disclosed are a fastening system and a method for fastening a fastening element made of a first material to a substrate made of a substrate material. A blind hole is made in the substrate, and a fastening element is anchored in the blind hole. A shaft of the fastening element defines a fastening direction and has a circumferential surface which is slanted or stepped in relation to the fastening direction.

A method of fastening a fastening element consisting of a first material to a substrate consisting of a substrate material, the method comprising:
- creating a blind hole defining a depth direction with a blind hole diameter in the substrate,
- providing a fastening element which has a shaft defining a fastening direction having an end face pointing substantially in the fastening direction and having a circumferential surface adjoining directly to the end face, wherein the end face has outer dimensions,
- driving the shaft into the blind hole to anchor the fastening element in the blind hole,
- wherein the outer dimensions of the end face exceed the blind hole diameter, so that when driven into the blind hole the shaft displaces a part of the substrate material in the depth direction and is welded on the substrate at the circumferential surface, and wherein the circumferential surface is slanted or stepped relative to the fastening direction.
A fastening system comprising a substrate consisting of a substrate material and a fastening element, which has a shaft defining a fastening direction having an end face pointing substantially in the attachment direction and having a circumferential surface adjoining directly to the end face, wherein the shaft is welded on the substrate, and wherein the circumferential surface is slanted or stepped relative to the fastening direction.
