This 10 inch extra capacity adjustable wrench has quickly become my favorite adjustable wrench to carry in my tool bag. The longer handle and wider wrench opening gives me added flexibility when minimizing my tool bag (to only carry one size adjustable). The extra wide jaw provides me a better gripping surface when loosing or tightening nuts and bolts. the wrench can be adjusted easily to fit small and larger size hex nuts and bolts. I even use it to raise and lower my 16 foot enclosed trailer jack. The 8 inch adjustable I used to carry is now just a back up wrench. Recommend it to everyone from the DIYer to the professional in the field.

The 15/16 extra capacity adjustable wrench is an excellent addition to my home tool chest! The small size allows use for all the small projects around the house and proved to be perfect for assembly of our new outdoor grill. It is well built and should last for a lifetime. Home Depot came through again with a quality product that will be of use around my house for some time to come.

Good tools are an investment. You could find a cheap adjustable wrench, they’re everywhere, but when when you grab this wrench and start to use it you’ll notice the difference right away. First, it’s a good size and it opens wide, making it versatile, even among other adjustable wrenches. It’s made of an alloy steel, and the finish is good, and it’s fairly light, a plus and a minus. The adjustment is smoooooth and tight, no slop or rattle you get with cheap adjustable wrenches. This one has a metric scale on one side and a US scale on the other.My only concern is the durability, in my short test I was able (unintentionally) to ding the wrench pretty easily.

Nice wrench. A bit heavier and bulkier than may be necessary, but it’s a quality piece. The tolerances are reasonably tight, though with little effort a company like Klein should be able to remove most of the play from the lower jaw. But the adjustment screw is the smoothest I’ve felt. Perfect balance, well made and nice feel to the handle. The jaws stay at set opening, no lazy travel.

I recently acquired a Klein 8” Adjustable Wrench. It is without a doubt the best wrench I have ever owned. The thoughtfulness that has gone into the design, balance and finish is amazing. Klein has done something with this 8” wrench that I have never seen before. The jaw capacity is 1⅛”, allowing for a more precise fit on nuts/bolts that are 1” in size and perhaps a bit worn or the need to work in a cramped space. Another unique aspect of this wrench is the measurement scale in both US standard and metric along the fixed jaw. It is finely etched and will definitely stand the test of time. This feature allows you to get the normal size adjusted quickly.

This is a compact adjustable wrench that has an extra wide opening for a wrench its size, making it very handy. The six-inch length fits into tight spaces and it provides a jaw capacity of 15/16th of an inch. Opening has a calibrated scale to help preset the wrench to fit. This wrench feels well made, opens and closes smoothly with little effort, has good gripping power, and is from a very good manufacturer. A great general purpose wrench to have in your toolbox.

The Klien 1-1/8 in. extra capacity adjustable wrench is made the way an adjustable wrench should be. Not only is it heavy duty. The adjustment mechanism is easy to use and it is very tight thus not allowing the jaws to slide around like some of the cheaper adjustable wrenches. Another nice feature is it has a metric and SAE scale along the sliding jaw, which is a time saver.

KLEIN TOOLS 1-5/16 IN. EXTRA CAPACITY ADJUSTABLE WRENCH This is an excellent addition to your tool bag. It is very study and well made of anodized steel. It’s heavier built than your run of the mill adjusting wrenches. It has great feel in your hand and as you can see in photos has easy (I could read it without my glasses) to read calibration of SAE on one side and metric on other on jaws. It has about 3/8 inch addition span in jaws for a little e extra duty.

1-1/8 in. Extra Capacity Adjustable Wrench Gadgetman DIY scale of dead easy, it’s a hand tool. This one is well made the worm gear turns easily, the jaws go from fully closed to wide open without any hiccups or stiff spots. This 6 inch adjustable wrench has a brilliant little add on in that it is bit a metric as well as SAE adjustable wrench it has a convenient scale printed on the stationary jaw SAE on one side and metric on the other. If nothing else you can see that If you have a 12 mm nut but not a 12 mm socket you can use a ½ inch socket in a pinch. Well made tool box staple.

Klein Tools once again has caught my eye. The 10 1/8 adjustable wrench is heat treated steel alloy construction. The high polished chrome finish will protect this adjustable wrench for years of service. The precision machines jaws and the knurled thumbscrew make for a very high quality adjustable wrench. But once you use this wrench you can feel the wrench jaws lock onto the nut. You know it wont slip busting up your knuckles. The etched scale on both side the tool is a nice feature. But probably wont last as long as a engraved scale would of lasted. With lots of choices of adjustable wrenches. This Klein Tool offers quality and an affordable choice. And will be in your toolbox for many years to come!

High quality adjustable wrench.The jaws on this Klein wrench are noticeably tighter (less slop) than most other adjustable wrenches. The adjustment screw contacts four “threads” instead of the more common three thread engagement. The area where your hand grips the wrench is wide and smooth, so the tool is comfortable to use. While rubber handles sometimes have their place, this one is plain steel, which makes it much easier to clean after the dirty jobs. The forging is crisp and nicely done. The jaw opens about 1-1/8″, which is really wide for a wrench that is 8″ in length. I do not usually pay attention to the size markings on the jaws of adjustable wrenches, but the markings on this Klein wrench are very clear and easy to read (English on one side, metric on the other). The overall shape of this wrench is what I call “Classic” – by that, I mean the hanging hole is round, not square, and the jaws are meaty and not pointed. This is a high quality tool which will give a lifetime of satisfaction to both professionals and tool-lovers alike. Highly recommended.

The 10 inch Klein Tool 1-5/16 adjustable wrench is a must have for every toolbox. Nice chrome finish which makes for easy cleanup. Smooth and easy on the hands. Very sturdy, functional, easy to use and well made. The adjuster has a convenient scale for helping you determine nut size with a metric and SAE scale that is very easy to read. The adjuster has some very well defined knurling, which makes for easy use too.

Klein has made a great adjustable wrench. You know its a winner when you first pick it up. The screw adjust smoothly and flush with the nut. When you tighten the nut you will notice that there is no flex in the wrench head, the jaws stay put and hold tight to the nut, no gaps forming around the nut. The weight is really good and it has great balance in you hand. You will notice that I measure a lot of tools to determine if the scale is accurate or even close and this one was spot on. Do like I am going to and get the full set of sizes.

I really appreciated the calibrations on the adjustable end of this wrench, they give me confidence in setting the right size for the bolt I am working with. At first I thought the overall size of the wrench was too small to get the torch necessary to tighten things down, but after using it I have come to appreciate the ability to access small spaces, I am glad I added this wrench to my tool box. I am planning on also adding the next larger size or two.

When this adjustable wrench arrived a few days ago i immediately put it to work. I used it to loosen a stuck on showerhead. This wrench is a nice addition to my toolbox. It has a nice weight to it and a good hand feel.It doesn’t appear to be a cheap Chinese made tool as Klein Tools have been around a very long time making QUALITY tools. I will surely take good care of this tool.

Overall a very nice adjustable wrench. The size and weight are good, has a very sturdy, strong, durable feel to it. Nice clean look ( for now) and easy to use. The extra capacity allows it to be used in more general applications so no need to keep around more tools. The adjuster works nice and smooth. Has markings on both sides of the head (metric ans standard) for a quick size reference.

This Klein Tools 15/16 inch extra capacity adjustable wrench is a well made tool that should last you a long time. It is six inches in length and has adjustable jaw that opens to 15/16 inch or 24mm. The adjustment is smooth and marked with a printed ruler on both sides. The end of the handle has the normal hole for hanging the tool or allowing you to clip it in or tie it off. A good tool.

The Klein Tools Adjustable Wrench is well made just as I would expect from such a reputable company.The 10 inch adjustable wrench is what I consider to be the best all-around size. It will handle most jobs. It gives me the impression of being well made. It has good weight indicating it’s tough and the operation is smooth. The chrome finish is nicely done and should protect the tool from rust when used in wet environments.Folks like me that are trying to avoid buying Chinese products will be happy to know it is made in Spain.Now for the negatives. It is advertised as being “extra capacity” and “specialized for bigger jobs in confined spaces”. I was disappointed to realize, when compared to my other 10 inch adjustable wrenches, the jaws did not open any wider. I’m not sure what makes it “extra capacity”. Also, for the price and reputation of Klein Tools, I was surprised to see the jaw measurements painted on rather than etched or stamped.Overall, it’s a nice tool and with proper use and care should last several lifetimes.

Another high quality adjustable wrench from Klein. These have nice tight sliding jaws, a four thread thumbscrew (instead of the more common three thread thumbscrew), nicely finished with good clean forging. The 6″ length is a convenient size for smaller fasteners, and it is nice that the jaw opens wider than most other adjustable wrenches of this size. The shape of the jaws is what I consider “traditional” – in other words, they have a rounded shape (not pointy, like some others), and have good thickness. I also like the feeling of the metal in my hands – there is just a bit of texture, so it doesn’t slip out of your hands like the polished tools do (especially when they get some oil or grease on them).This is a really good tool. Don’t loan it out, don’t hit it with a hammer, keep it out of the rain, and this wrench will still put a smile on your face 30 years from now.

I didn’t know that an adjustable wrench could be so precise, or so solid.This is a finely machined tool. If you are used to an adjustable wrench that feels sloppy, loose and constantly needs tightening on the bolt, then this is a real eye-opener. There is absolutely no gap between the jaw and the main body of the wrench, yet it slides smoothly and precisely with absolutely no wobble. The knurl also rotates smoothly, and is also perfectly mated to the gear teeth with at least four teeth in contact at all times, some brands only have two in contact. I have never seen a wrench constructed with this degree of precision, and I have owned many brands, from high-end to cheap.The body of the wrench feels good in the hand, well balanced with no casting irregularities, and it is not chrome-plated like some brands, which I have had flake off.An engraved gauge on each side lets you know the size of nut or bolt that you are working with, metric on one side and inches on the other. This is a professional’s tool that will last a lifetime, and the 8 inch size is good for the majority of normal work. If I could only ever own one wrench of any kind, this would be the one.
