Since the working spaces are very constricted when screwing work on the bike, tools are necessary with which users can work successfully even in such situations. Narrow working spaces require additional attachment points of the tool. So can open-end wrenches be modified in such a way that the tool's attachment possibilities are increased? The combination of the 7.5° swiveled jaw and the double hexagon geometry results in a doubling of the attachment points. With a repeated 180° rotation of the wrench around the longitudinal axis during tightening, there are four attachment possibilities and nuts or screw heads can be "gripped" every 15°. The Joker 6003 with its smart jaw geometry significantly expands the range of users in tight installation spaces. The Joker 6003 finds the respective attachment point by itself, so to speak, after each turn. The slim yet robust ring side is angled at 15° to the tool axis. The high-quality surface coating provides high and long-lasting corrosion protection. With tool finder Take it easy: color coding according to sizes. The Joker bag is suitable for attachment to walls, shelves, workshop trolleys and the Wera 2go system thanks to the Velcro system on the back.
