High-quality, metric double spanner from Wera: Everything a wrench can do and so much more. Faster, better, more beautiful. A real Joker. The new generation of double open-ended spanners. For hexagon screw heads and bolts. With holding function by a metal plate in the open end, which reduces the risk of losing screws and sockets. With its extra hard teeth the exchangeable metal plate in the open end secures screws and sockets and reduces the risk of slipping. The integrated end stop can prevent the screw head from slipping down and allows application of high torques. The double hexagon geometry ensures a positive connection with the screw or bolt and thus reduces the risk of slipping. A return angle of only 30° avoids time-consuming rotating of the wrench whilst screwdriving. The special forge geometry allows a high torque transmission and high bending stiffness. Made of high-performance chromium molybdenum steel with nickel-chromium coating for high corrosion protection. With tool finder Take it easy: colour coding by size.
