The wera 7880 joker xxl spanner insert is a self-setting insert spanner designed for use with wera click-torque x and xp series torque wrenches fitted with a 14x18 mm mounting. Compatible with hexagon screw heads and bolts across wrench sizes 24 32 mm, it covers both metric and imperial dimensions within its range. Unlike fixed-size spanners, the 7880 joker xxl automatically adjusts to the required size as it is applied to the fastener, meaning a single tool effectively replaces several individual spanner sizes. The continuous, parallel jaws self-set upon contact, while an integrated lever mechanism clamps securely onto the hexagon head to significantly reduce the risk of slippage or fastener damage. The built-in mechanical ratchet function allows fast, consistent tightening without the need to remove and reposition the tool between turns. Using the corner-width rectangular prisms within the jaw, a return angle of just 30 is achievable particularly useful when working in restricted spaces. A laser-engraved, abrasion-proof qr code is included to help determine the correct torque value for the wrench and insert combination in use.
