6004 Joker

Self-setting, adjustable spanner

Many users want a universal screwdriving tool with the widest possible range of applications. It should be a single tool for several metric and inch dimensions. It should automatically adjust to the different screw sizes. It should grip securely, not damage anything and allow a high working speed. The stepless and parallel guided jaws replace several open-end wrench individual dimensions.

Automatic and continuously self-adjusting

The wrench finds the required size by itself when applied to the nut or bolt without adjustment.

Ratchet mechanism for fast work

The ratchet function in the jaw ensures fast and continuous work.


The parallel smooth jaws allow surface pressure and can thus avoid rounding of the nut or bolt head.

Continuously automatic self-adjusting

The required size adjusts itself steplessly when applied to the hexagon nut or screw.

Practical hanging hole

The hanging hole allows the Joker to be neatly stored on the workshop wall.
