    Small Joker

    Posted by Stephanie Wolz on Apr 14th 2022

    A lot of my tools are small because I need them to be comfortable in my hands. I got the small Joker to give it a try. It’s got a good hand feel, it’s solid and well made. I’ve yet to be able to turn anything with it which is why it’s gave it four stars. I can’t fully judge it until I use it. It’s a neat tool for sure and a great addition to my “weird” tools.

    Self-adjusting wrench

    One of a kind smart design, grabs the screws/bolts firmly, I just wish the minimum size could be smaller than 7/16.

    Just love it. I work with Festo fittings and often find that identical fittings require different sized wrenches, depending on the year they were made. This makes it so nice to not have determin if its a 10mm or 11mm, and to just get the work done!!

    Wera 020100 joker 6004 self-setting wrench

    This is an interesting wrench that fills a gap for someone who works on a SAE and Metric equipment. In this case area between 8mm-13mm heads which includes 7/16 often used on a lot of equipment. Fits well in the pocket, seems strong, the rachet feature and off angle features both work well. I use this one with a Joker 10-13 double open end wrench and I can do about 75% of my work with those two in my pocket.

    Purchased to see how well the joker adjustable wrenches hold up. I'm really happy with it and how well a ratcheting system works on an open wrench. Its no where near as fragile as it would seem. The only downside is the size of nuts/bolts you can actually grab. If i had to buy again I would've purchased the whole set from the start.

    Amazing tool

    Posted by Jonathan carmona on Sep 14th 2020

    I am in the plumbing trade and this is hands down the best adjustable wrench for I have owned. Great for smaller nuts. Has yet to slip once. Great tool 10/10 would recommend

    Fun little wrench! Once you get used to it, its pretty handy. Used it to tighten up some furniture already. The action needed takes space, so its not for tight access work or backing nuts.

    Very well made

    This is the best self setting wrench I have ever purchased. I'm so impressed with it, I ordered the other two sizes available. The price may seem a little high, but it is well worth it when you see and feel the products build quality. If you are in the market for an adjustable wrench, look no further than this.
