5-piece open-end ratchet wrench set, metric sizes; on a mounting rail. The Joker 6000 open-end ratchet wrench features a holding function for hex screw heads and nuts. The interchangeable metal plate in the jaw secures screws and nuts with extra hard teeth. The integrated end 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, reducing the risk of slipping. A return angle of only 30° on the jaw side avoids time-consuming turning of the wrench while screwing. The ratchet mechanism on the ring side has an exceptionally high tooth count of 80 for flexibility even in tight spaces. The special forging geometry ensures 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. The clamps on the rail ensure a perfect hold of the tools. The rail securely attaches to metal surfaces with a strong magnet. Alternatively, the rail can also be screwed to a wall.
