High-quality metric double open-end wrench from Wera: everything a wrench needs to do, and much more. Faster, better, more beautiful. A true joker. The new generation of open-end ratchet wrenches. For hexagonal screw heads or nuts. Features a holding function with a metal plate in the jaw that reduces the risk of losing screws and nuts. The replaceable metal plate in the jaw secures screws and nuts with extra hard teeth and minimizes the risk of slipping. The integrated end stop can prevent slipping off the screw head and allows for the application of high torque. The double hexagon geometry ensures a positive fit with the screw or nut, thereby reducing the risk of slipping. A return angle of only 30° avoids time-consuming turning of the wrench while screwing. The special forging geometry provides high torque transmission and high bending stiffness. Made from high-performance chrome-molybdenum steel with a nickel-chrome coating for excellent corrosion protection. With the tool finder "Take it easy": color coding by size.
