The laser-engraved, abrasion-proof QR code makes it easier to determine the correct torque value depending on the torque wrench and insert tool used. Simply scan with your smartphone or tablet (if available, both QR codes: torque wrench and insert tool). A website opens automatically which recognizes the scanned tools (no app needed!). Then enter the required torque value; the corrected value is determined automatically. No need to use formulas/calculations.

Torque Advisor
Drive 14x18 mm
For torque wrenches from the Click-Torque X series with 14x18 mm mounting.
Automatically and continuously self-setting
With its automatically and continuously gripping parallel jaws, the 7880 Joker covers all dimensions within the potential operative range. The tool finds the required size by itself when attaching it to the bolt or screw.
Joker 7880: gentle to the screw
The parallel, smooth jaws of the 7880 Joker offer a seating stress and can thus prevent the nut or screw head from rounding, which can occur when power is transmitted over corners.
Joker 7880: ratchet mechanism for quick working
The ratchet feature in the jaw ensures fast and consistent screwdriving without removing the tool.
Joker 7880: low return angle
The corner-width rectangular prisms in the jaw allow a return angle of only 30°.

Product description
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. 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.
