High-quality metric double open-end wrench from Wera: everything a wrench should be able to do, and much more. Faster, better, more beautiful. A true joker. The new generation of open-end ratchet wrenches is suitable for hexagonal screw heads and nuts. It features a holding function through a metal plate in the jaw, which reduces the risk of losing screws and nuts. The replaceable metal plate in the jaw secures screws and nuts with extra hard teeth, minimizing the risk of slipping. The integrated stop prevents slipping off the screw head and allows for the application of high torque. The double hex geometry ensures a form-fitting connection with the screw or nut, thus reducing the risk of slipping. A return angle of just 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. Equipped with the "Take it easy" tool finder: color coding by size.
