5-piece open-end ratchet wrench set, metric sizes; on a clamp rail. The Joker 6000 open-end ratchet wrench features a holding function for hex screw heads or nuts. The replaceable metal plate in the jaw secures screws and nuts with extra hard teeth. The integrated stop prevents slipping off the screw head and allows for high torque application. The double hex geometry ensures a positive fit with the screw or nut, reducing the risk of slipping. A return angle of only 30° on the jaw side avoids the time-consuming need to turn the wrench while working. 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. With the "Take it easy" tool finder: color coding by size. The clamps on the rail ensure a perfect hold for the tools. The rail securely attaches to metal surfaces with a strong magnet. Alternatively, the rail can also be mounted on a wall.
