Many users want a universal screw tool with the widest possible range of applications. It should be a single tool for several metric and imperial dimensions. It should automatically adjust to the different screw sizes. Secure packing, do not damage anything and allow a high working speed. With the infinitely and parallel guided jaws, several wrench-individual dimensions are replaced. The required size can be adjusted continuously by itself when the hexagon nut or screw is fitted. The integrated lever mechanism securely clamps the hexagonal screw or nut between the jaws, which significantly reduces the risk of slipping and damage.
The ratchet function ensures quick and continuous screws without putting off. By using the corner-width prisms, a back-swivel angle of only 30° is possible. The one-leg design in conjunction with the ratchet function and the corner width prism allows working even in narrow spaces.
The adjustable Joker 6004 is the universal screwing tool. Self-adjusting. Packing. Ratcheting.
