<p>A screw (1) is to be used to secure two components (8 and 11) together by screwing the screw (1) into a blind hole (7) in component (8). Component (11) has a correspondingly larger through hole (13). The shank (20) of the screw has a self-tapping thread (3). A groove (4) extends from the free end of the screw shank (2) over at least one thread pitch (S) approximately parallel to the axis of the screw shank. At least the first thread (3') crossing the groove (4) extends from the rearward limiting side (5) of the groove (4) in the direction of insertion of the screw (1). This first thread (3') cuts the thread in the wall of the blind hole (7), whereby the material removed in cutting the thread is held in the relatively large groove (4).</p> |
