This ratchet screwdriver revolutionises the screwdriver: Wera's sturdy yet smooth ratchet mechanism makes it possible to fasten or loosen screws without releasing the tool. The hexagonal reverse direction switch made from robust, die-cast zinc alloys prevents the tool from rolling on the work top and allows for easy switching. Torques of up to 50 Nm can be transmitted in both directions, with an additional center position for making fine adjustments. Bits are easily changed by insertion with the function for rapid bit change and retention. Pouch closed 170 x 120 x 40 mm. Overall length mounted 220 mm.
