Abstract

The sheet metal work piece (12) is, by pressing or a similar material deforming but essentially not material separating working step, provided with at least one depression (15) with a depending wall (19). The wall ends at its bottom with material thinning or a small hole with racks around it. The screw (25) is designed in such a manner that it can ream its way through the sheet metal and form counter threads in the depending wall (19) of the depression. <IMAGE>
