Abstract: A method is disclosed for inserting a nail into at least one component part, the nail having a nail head, a nail shank and a nail tip. The method includes (i) arranging the at least one component part, (ii) positioning the nail, and (iii) driving-in the nail. A force is applied to the nail in the direction of the component part, such that it is pressed into the at least one component part. In addition to the application of force, vibrations are coupled into the nail, and a multipart nail is used.

Abstract: A self-piercing rivet of a special rivet geometry is described, which in particular is suitable for joining high strength steel sheets, but can also be used for other metal sheets. The self-piercing rivet is in particular characterized by a special underhead geometry as well as a special geometry of the rivet foot (cutting region). Thus the self-piercing rivet has an underhead chamfer which with a radial plane of the self-piercing rivet encloses an angle of 20°+5°/?5° and merges tangentially into the cylindrical outer surface of the rivet shank via a radius. In the region of the rivet foot the self-piercing rivet has a plane shank face, which extends essentially at a right angle to the rivet axis and which merges “smoothly” into the cylindrical inner surface via a shank inner surface and a radius.
