Abstract

Die vorliegende Erfindung betrifft einen Schraubenausdreher zum Ausdrehen von Schraubenstümpfen abgerissener Schrauben, der sich mit einer Einschraubzone in eine Axialbohrung des Schraubenstumpfes einzieht, so tief, daß ein Drehverbundstück entsteht. Zur Erhöhung des in den Schraubenstumpf eingeleiteten Drehmoments ist die Einschraubzone des Schraubenausdrehers von einer flachen Einkerbung eingeschnitten, die sich mit einer Quetschkante in das Material des Schraubenstumpfes so tief einarbeitet, bis der Schraubenausdreher fest sitzt.
