The Wera Joker is an innovative combination spanner with a unique jaw design. Its clever design means that it does everything that a conventional combination spanner does, and more. Made from durable chrome molybdenum steel and coated with corrosion resistant nickel-chrome, the Joker is a truly high-quality spanner. Advantages of the jaw end An innovative metal stop-plate means that the Joker can hold a fastener in position for screwdriving, making assembly easier and quicker. An integrated lL off the fastener. The jaw allows safe screwdriving, even at high torques, due to its extra hard and toothed gripping plate, which prevents slippage of the fastener and helps to eliminate rounding. A reverse travel angle of 30 allows the spanner to be used in confined spaces, where a conventional open-end spanner cannot be used. Advantages of the ratchet end Ultra-fine toothing, with 80 teeth, allows flexibility even in confined spaces. Very long service life, even when used at high torque.
