6-piece set. Self-adjusting wrench Joker 6004 with ratchet function. The continuously adjustable and parallel-guided jaws replace multiple individual wrench sizes. Suitable for metric (7.0 to 32.0 mm) and imperial (¼" to 1 1/4") hex screws and nuts. The required size automatically adjusts when applied to the hex nut or screw. The integrated lever mechanism securely clamps the hex screw or nut between the jaws, significantly reducing the risk of slipping and damage. The ratchet function allows for quick and continuous screwing without repositioning. The use of corner width prisms enables a return angle of only 30°. The single-arm design combined with the ratchet function and corner width prism allows for work in tight spaces. Comes in a sturdy roll-up bag.
