6004 Joker XL Self-Adjusting Flat Wrench

The Joker 6004 open-end wrench covers all sizes within its application range thanks to its automatically and continuously adjustable jaws, which move in parallel. The required wrench size is determined automatically when the wrench is placed against a nut or bolt, without the need for manual adjustment.

The smooth, parallel jaws of the Joker 6004 wrench prevent the head of a bolt or nut from becoming rounded due to surface pressure, which can occur when force is transmitted through the corners.

The ratchet function in the jaw ensures fast and smooth tightening without interruption.

Thanks to the prisms in the jaw, the working angle is just 30°.

Thanks to its hanging hook, the Joker wrench can be hung on a workshop wall.
