<p>A knurled nut (2) is joined to the shaft of the screw (1) from below. A first pin (3) is guided transversally through a circular bore (9) extending into a longitudinal slot (10) at the opposite side of the shaft. A second pin (5) is guided horizontally through the shaft below the first (3). A plunger (6) is accommodated in an axial bore. For use the lower end of the shaft is positioned on top of the parts to be connected and the nut (2) turned to the right. The diagonal pin (3) is pushed into a horizontal position pressing the second pin (5) and/or the plunger (6) against the parts.</p> |
