Self-setting insert spanner, for hexagon screw heads and bolts, for torque wrenches from the Click-Torque X and XP series with 14x18 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.
