Abstract

Die Erfindung betrifft ein Schraubwerkzeug mit einem eine Achse definierenden, in einem Gehäuse (1) gelagerten Drehmomentabtriebskörper (4), mit einem eine Vielzahl von Vertiefungen (6) aufweisenden Drehmomentübertragungsabschnitt (5), mit einem von einer Kraft eines Kraftspeichers (19) vorgespannt in zumindest eine der Vertiefungen (6) eingreifenden Drehmomentübertragungskörper (7) zur drehmomentübertragenden Kopplung des Drehmomentübertragungsabschnittes (5) an das Gehäuse (1), welche drehmomentübertragende Kopplung aufgehoben ist, wenn der Drehmomentübertragungskörper (7) flankengesteuert bei Überschreiten eines Grenzdrehmomentes gegen die von einer Einstelleinrichtung (20) einstellbare Kraft des Kraftspeichers (19) die Vertiefung verlässt. Zur gebrauchsvorteilhaften Weiterbildung wird ein von einer Freigabestellung in eine Blockierstellung verlagerbares Umschaltglied (12), welches in der Freigabestellung das Vertiefungsverlassen des Drehmomentübertragungskörpers (7) ermöglicht, in der Blockierstellung aber blockiert, vorgeschlagen.
