Wera Joker Combi Ratchet Spanner Set Of 4 Blister Packed Wera Joker is an innovative combination wrench with a unique jaw design. Its clever design means that it does everything that a convention combination wrench does & more. Made from durable chrome molybdenum steel & coated with corrosion resistant nickel-chrome, the Joker is a truly high quality wrench. Advantages of the jaw end: An innovative metal stop-plate means that the Joker can hold a fastener in position for screw driving, making assembly easier & quicker. An integrated limit stop acts as a depth stop to prevent the tool slipping off the fastener. The jaw allows safe screw driving, even at high torques due to its extra hard & toothed gripping plate, which prevents slippage of the fastener & helps to eliminate rounding. A reverse travel angle of 30 allows the wrench to be used in confined spaces, where a conventional open-end wrench 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. Set of 4 Joker spanners: 10 mm., 13 mm., 17 mm. & 19 mm., supplied in a blister pack.
