A press-fit connection between a high-strength component and a press-fit element is characterized by a non-circular previously made hole into which the press-fit element having a collar is inserted. Here, the collar is merely upset and pressed against a hole rim without embracing an underside of the component. Preferably, the hole rim is widened in a longitudinal direction such that a form-locking connection acting in opposition to the longitudinal direction is formed. The non-circular hole geometry is produced with the aid of a punch of circular cross sectional geometry, in that a cutter of the punch has leading and recessed cutting regions, with the result that disrupted partial regions are formed.
