Abstract
The invention relates to a method for anchoring a joint element () in a metal sheet () so as to be secured against rotation, the hardness of the metal sheet being equal to or greater than the hardness of the material of the joint element. A locking and securing portion (), which protrudes away from a head () of the joint element, is inserted into a joint opening (), which is provided in the metal sheet and which has a cross section that deviates from the circular shape, such that an edge of the joint opening forms at least one region with a maximum distance to a central axis of the joint opening and at least one region with a minimum radial distance to the central axis of the joint opening, and the head of the joint element rests against the metal sheet after being anchored.
