Description

Self-adjusting socket wrench, for hexagonal screw heads or nuts, for Click-Torque X and XP torque wrench series with 14x18 mm holder. Covers all metric and imperial dimensions in each application area. The continuously variable, parallel jaws replace several individual fork-spanner dimensions. The required size is infinitely adjustable by itself when you place it on the hexagonal nut or screw. The integrated lever mechanism securely engages the hexagon screw or nut between the jaws, WAS significantly reduces the risk of slipping and damage. The ratchet function is provided for fast and continuous screwing without setting. By using the corner width prisms, a return angle of traverse of only 30° is possible.
