Many users wish to have a universal screwdriving tool with the widest possible range of applications. It should be a single tool for multiple metric and imperial dimensions. It should automatically adjust to the different screw sizes. It should be safe to grab without damaging anything and allow for a high working speed. The continuous and parallel jaws replace several single spanner dimensions. The required size is automatically and continuously set when attaching the tool to the hexagon bolt or screw. The integrated lever mechanism securely clamps the hexagon screw or bolt between the jaws, which significantly reduces the risk of slipping or damage. The ratchet function ensures fast and consistent screwdriving without removing the tool. Thanks to the corner-width rectangular prisms, a back-pivoting angle of only 30° can be realized. The single-arm design in conjunction with the ratchet function and the corner-width prism make it possible to work even in confined spaces. The adjustable Joker 6004 is the universal screwdriving tool. The compact folding pouch with four adjustable Joker 6004 spanners covers all metric and imperial dimensions in applications from 7 to 19 mm or 1/4″ to 3/4″. Automatic and continuous gripping of hexagon screw or bolts. Lever mechanism when gripping avoids slippage and damage. Fast and consistent screwdriving without removing the wrench thanks to mechanical ratchet function. Back-pivoting angle of only 30° through placement in the corner-width rectangular prisms in the mouth. If it is a weekend or a holiday, the time will be extended accordingly.
