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.

The primary feature is that with this wrench, the more pressure you apply, the tighter it grips, greatly reducing the chance of the tool slipping off or damaging the flats of the fastening. Secondly, because the jaws are spring-loaded, the wrench can be slipped back around the flats to resemble a ratchet, without having to set or adjust anything, which is very handy. Given these advantages over a conventional adjustable wrench, I can't see myself ever using one again if I have one of these Wera wrenches to hand. Given the price, the construction and finish are what you would expect and will give long service. A lovely tool that adds something very worthwhile to your armoury.

Wish they kept the handle size as thick as smaller versions. Other than that great tool. Speeds up any fastening procedure
This wrench has already gotten me out of trouble, a little learning curve on how to make it work but it does what it is designed to do… I bought the small one and it helps you get into those bulkheads of hoses, tight spots with limited turning space.
this tool is very useful and is able to grip slightly rounded off hex heads and is very easy to use and a great addition to my tool boxRobert Cook
Well packaged. The wrench is very nicely engineered and super handy for smaller projects involving bolts
Great tool actually and the usual wera quality too , very useful in the plumbing trade and great price too
Found the Wera joker spanner a great addition to my tool kit. Very handy with the ratchet action, I still us adjustable/ shifting spanner but using these more and more.
I am a big fan of Wera. There tools are well made and well thought out. These self adjusting spanners are an ideal addition to my workshop. Well made, and very easy to use. They come in a range of sizes so make sure you get the right size range to suit your work.
