The Wera Joker 6003 ring spanner with its special mouth geometry – mouth side pivoted by 7.5° and the double hexagon profile – doubles the placement possibilities when repeatedly turning the wrench 180° around the longitudinal axis. Bolts and screw heads can be "accessed" every 15°. The Joker 6003 will automatically find the respective placement point after every turn. Bolts and screw heads can be "accessed" every 15°. The Joker 6003 will automatically find the respective placement point after every turn. Joker 6003: For pivoting angles under 30° Thanks to the mouth side pivoted by 7.5°, double hexagon geometry and an adjusted application method (placement – screwdriving – turning – replacement – screwdriving – turning, etc), even screwdriving challenges allowing a pivoting angle of less than 30° can be solved. Double-hex geometry The double hexagon geometry on the mouth and ring sides secures the positive connection with the screw head or bolt and reduces the risk of slipping. The ring side is angled at 15° to the tool axis to prevent injury.
