The first bore (3a) opens into a smaller, second bore (3b) of the first component (2a), and said second bore (3b) is provided with a left-handed thread (8) in which there is screwed a tubular extension (5c) which is arranged coaxially with the bore in the base (5b). The screw (1) is screwed, through the bushing (5a, 5b) and the tubular extension (5c), into the second component (2b) by means of its right-handed thread (7). A cap (6a), having an insert (6b) which is connected to the screw head in a positively locking manner, is fastened on the bushing (5a, 5b) by a welding bead (4).
