Features
Self-setting insert spanner, for hexagon screw heads and bolts, for torque wrenches from the Click-Torque X and XP series with 9x12 mm mounting. Covers all metric and imperial dimensions in the respective field of application. With its continuous and parallel jaws, the tool replaces several single spanner sizes. The required size is automatically and continuously set when attaching the tool to the hexagon bolt or screw. The integrated lever mechanism securely clamps the hexagon screw or bolt between the jaws, which significantly reduces the risk of slippage or damage. The ratchet feature ensures fast and consistent screwdriving without removing the tool. By using the corner-width rectangular prisms, a return angle of only 30° can be achieved.
