## Overview

The Wera 6004 Joker XS is a compact, self-adjusting spanner designed for both metric and imperial hex bolts from 7-10mm and 1/4"-3/8". Featuring a slip-resistant lever grip and a mechanical ratchet, it enables fast, damage-free screwdriving even in tight spaces with a minimal 30° return angle. Engineered for professionals, its durable brushed finish and universal fit replace multiple wrenches, saving time and effort on every job.

## Description

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 return 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. Self-setting. Gripping. Spanning.

Review: Wow, cannot wait to purchase the right size. - I did not order the correct size but it is the best tool you can have for those small, nearly anatomical impossible placement of a connection. If your young and like to spend more time on the floor to install plumbing, keep doing it the hard way. This is a time and back saver.
Review: it just works - To my fellow AMTs wondering if this gimmick actually works and is worth the 30 bucks because you've never seen anyone using it: yes, this is the real deal.

A: Yeah I thought the same. But then I got it and dident want it. But I saved it and gave it to my grandson. That's all it did.

### ⭐ Broke on a 10m bolt removal. DO NOT PURCHASE
*by R***E on March 28, 2022*

This isn’t a joker….it’s a joke. First off, I thought when I bought this that it was the bigger version. It was a lightning deal at $33 so I bought it. When it arrived, it was TINY. I was skeptical because the tool clamps down on a nut or bolt head during rotation. To me, that seems overly complex. The range is slightly over 3mm so if you think about it, it’s not convenient. I roll a tool cart with all of my smaller wrenches and usually land the right one the first time. I don’t need a self adjusting wrench this small and you shouldn’t either. It’s existence is pointless. But that is besides the fact that it broke on the first bolt it touched. My instincts were right: I was removing a bolt from a lightweight strut cartridge on the hood of an Acura. At first, it had a solid grip as the bolt head was square in the jaws. I applied pressure and *piiiingg*…something flew out of the tool as it released the bolt head under slight pressure from my right hand. Luckily I knew to press open handed as to not jamb my fist into sheet metal and the strut assembly. Wow. I was left with this joke(r), dangling it’s now broken head in a loose manner. I could only speculate that it was a spring of some kind but it was so small, I never found it. For the $ I paid for this tool, I was not happy. I got my torque wrench out, set it on inch pounds and loaded the bolt head with 20 INLB before it gave. Unbelievable. I immediately went to my orders page on Amazon but wouldn’t you know it: I missed my return window by 3 days. That’s because the tool is so useless that it sat in the tool chest for the opportunity to use it. FAIL Hence my negative review. I did not apply the tool in the wrong direction, either. I was within range of the marking on the tool which is also a mystery: 7 1/4 to 10 3/8. Is that metric or imperial? It appears to be both which makes no sense to me. Wera, if you are reading this: I’m never buying one of your tools again. If I see your tools in a buddys tool kit, I’m going to laugh at him and tell him he bought junk. Because that is what this wrench is…Junk.
