Abstract (en)
[origin: EP0925878A2] The screw driver has a turning part (10) and a setting part, e.g. a setting screw (20). The screw has setting markings (24), which are visible from outside, and act with a setting scale (26) on the hand grip (14). The setting scale indicates the preset torques. The turning part is axially replaceable by other parts, because the torque limiter positively holds the replacement part with its holder part, in its axial position in the hand grip. The torques adjustable by the torque limited are below 10 Nm, especially between 5 and 6.5 Nm.
