Wera 7880 Joker L 16-19

Self-adjusting insertable open-end wrench for hexagonal screw heads and nuts, suitable for Click-Torque X and XP series torque wrenches with a 14x18 mm drive. Covers all metric and imperial dimensions within the respective application range. The continuously adjustable and parallel-guided jaws replace multiple individual open-end wrench sizes. 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. By utilizing corner width prisms, a return angle of only 30° can be achieved.
