## Description

From the manufacturer Key Features Self-Setting The automatic and continuously gripping parallel jaws ensure that the Joker 6004 will automatically find the required size when placed on the bolt or screw, no setting required! Gentle To The Screw The parallel smooth jaws of the Joker 6004 allow surface pressure and therefore prevent any rounding out of the bolt, which often occurs during high torque transfer on corners. Ratchet Mechanism The ratchet function in the mouth allows you to work at a consistently fast speed, without having to remove the tool. Low Back Pivoting Angle Thanks to the corner-width recesses you can work in confined spaces with as little as 30° clearance. Wera 6004 Joker S self-setting wrench, 10-13 & 7/16"-1/2" x 154 mm, 05020100001 Many users wish to have a universal screwdriving tool with the widest possible range of applications. It should be a single tool for multiple metric and imperial dimensions. It should automatically adjust to the different screw sizes. It should be safe to grab without damaging anything and allow for a high working speed. The continuous and parallel jaws replace several single spanner dimensions. 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 slipping or damage. The ratchet function ensures fast and consistent screwdriving without removing the tool. Thanks to the corner-width rectangular prisms, a back-pivoting angle of only 30° can be realized. The single-arm design in conjunction with the ratchet function and the corner-width prism make it possible to work even in confined spaces. The adjustable Joker 6004 is the universal screwdriving tool. Self-setting. Gripping. Spanning.

Review: Quality - I had looked at these for a while and for the price I couldn’t justify buying them. Then I tried a workmate’s and was sold. I ended up buying 2 different sizes and as a pipe fitter making up valves and tightening up fittings, these are so much easier and quicker than using adjustable spanner’s. Usual Wera quality means they are a must have addition to my toolkit.
Review: I always wanted one but now my son does all the pipe work he loves it - Not cheap but a great tool ease of use good grip value for money

Not cheap but a great tool ease of use good grip value for money

### ⭐⭐⭐⭐⭐ A really cost effective tool
*by R***R on 10 November 2025*

Brilliant little spanner. Does away with a lot of spanners you'd need otherwise and far easier to use than a conventional adjustable spanner.
