Self-setting Wera insert spanner for bolts
- Automatic continuous jaw adjustment: You instantly grip hexagon screws from 19 to 24 mm without swapping individual insert spanner sizes.
- Secure slip-free lever grip: The integrated lever mechanism firmly clamps fasteners to eliminate slippage and prevent damage to bolt heads.
- Rapid ratcheting working action: You work continuously without removing the tool thanks to the built-in ratchet function with a 30° return angle.
With the Wera 7880 Joker XL self-setting insert spanner, you handle demanding pipework and hydraulic fastening jobs with speed and precision. Featuring a 14 x 18 mm drive, this insert tool fits seamlessly onto Click-Torque X and xp series torque wrenches. Its smooth parallel jaws automatically and continuously adjust to hexagon bolts and nuts from 19 to 24 mm and imperial sizes from 3/4" to 15/16", eliminating frequent tool changes. The built-in lever mechanism provides a firm, slip-free grip that prevents corner rounding and damage to fasteners. Thanks to the mechanical ratchet action with a low 30° return angle, you work continuously and efficiently even in tight spots.
Scope of delivery

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.

Features and benefits
- 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.
- For torque wrenches from the Click-Torque X series with 14x18 mm mounting.
- 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.
- 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.
- The ratchet feature in the jaw ensures fast and consistent screwdriving without removing the tool.
- The corner-width rectangular prisms in the jaw allow a return angle of only 30°.
- Safe working and rapid tool change thanks to the pin lock of the insert tools.
- The insert tools are suitable for high loads thanks to their chrome-vanadium steel design.
