An adjustment screw 1 is essentially composed of three parts, namely of a threaded segment 2, of an inner adjustment screw 3 and of a screw body 16. The screw body 16 and threaded segment 2, which may be in one part or a number of parts, are each provided with an external thread and with an internal thread. Claw-shaped grooves lie diametrically opposite one another in the screw body 16. The grooves have oblique flanks 24 which converge in the direction of the interior of the screw body. The single-part threaded segment 2 is composed of two threaded legs 51, 52, which are connected to one another by a web 53, and has a cross-section in the form of an elongate U. The likewise oblique flanks 25 of the legs 51, 52 of the threaded segment 2 are seated in a precisely fitting manner on the flanks of the grooves 31 of the screw body 16 when the threaded segment 2 is introduced into the screw body 16. The inner adjustment screw 3 has a hexagon socket 19 and an external thread 20 which is screwed in by means of a thread 50 in the through-passage hole 30 of a hexagon 21 of the screw body 16. A pin 18 of the inner adjustment screw 3 butts, with a pressure fit, on the web 53 of the threaded segment 2. Rotation of the inner adjustment screw 3 effects an axial displacement of the threaded segment 2 with respect to the screw body 16. The axial displacement of the threaded segment 2 with respect to the screw body 16 results in mutual abutment of the threaded flanks and thus to a largely ... Original abstract incomplete. <IMAGE>
