Wera Joker Self-Setting Spanner
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 should allow for high working speeds. With its continuous and parallel jaws the Joker 6004 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 back-pivoting angle of only 30° can be achieved. The single-arm design, in conjunction with the ratchet feature and the corner-width prism, makes it possible to work even in confined spaces. The adjustable Joker 6004 is the universal screwdriving tool.

Excellent bit of kit to have in your toolbag. Very well built and self adjusts exactly as described. Adjustable size means you have to carry less spanners.

These spanners are a great new approach to reaching difficult nuts and bolts.
It’s a weird little wrench and takes some getting use to. But I’ve used it a few times now in spaces that were too tight for a socket and my ratcheting box wrenches were too far away. Works surprisingly well. It did slip a couple of times but I chalk that up to my inexperience.
The constantly adjusting mechanism is ultra precise and turns any tool you are using with them (PZ, Allen, torx, etc ...) Into a ratchet device. So, not cheap but in this instance, you do get what you pay for.
Amazing little tool!
Wera what a brilliant tool, I bought this tool for bolting up kitchen worktops the hard to reach one,s. I use the wera joker for the rest.
No a great plumbing tool. Especially for the price of 40.00. Better of with knipex.
Quality is as expected, you get what you pay for and this is no exception. Highly recommended
