Self-adjusting push-in open ring spanner, for hexagon screw heads or -Nuts, for Click-Torque X and XP series torque wrench with 14x18 mm mounting. 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 built-in lever mechanism holds the hexagonal screw or -Nut between the jaws securely in, 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.
