Abstract
A method of connecting a metallic bolt to a plastic work piece is shown and described. The object to provide a method which makes possible a reliable connection between metal workpieces on the one hand and plastic workpieces on the other hand is achieved in that a first plastic work piece and a metallic bolt are provided, and in that the bolt is pressed into a surface of the first plastic workpiece, the bolt being rotated during the pressing-in, and the rotational speed of the bolt being selected in such a way that the first plastic workpiece is plasticized, so that the bolt is anchored in the first plastic workpiece in a positive-locking manner after the rotation is stopped.
