The Only Brand of Adjustable Worth Having
In total opposition to the Bahco Stilson wrench I've just reviewed that was a bit low end, here we have the tool that made Bahco what it is. The humble but ever so useful shifter. Or adjustable wrench for non marine engineers.And being a Bahco shifter you have in your hands the tool that generations of engineers have used to keep ships afloat and sailing from port to port. I don't think I'd be exaggerating to suggest that more than a few ships made it because the bloke in the sweaty boilersuit had in his back pocket a trusty Bahco shifter which nipped up the pipe or nut that would have stopped the job. I know I have. In marine engineering circles the Bahco has almost mythical status that is ingrained from the moment you step onto a ship as a cadet - at least when the UK had a merchant navy that is.The reason we love them so much is because they are near indestructible. Its no exaggeration to say that engineers on ships abuse tools more than anyone else, mostly because sometimes you have to. I've put a six foot pipe on a Bahco and used it to tighten a nut on a steam pipe with considerable force and not broken it.And they stay usable. One of the big differences between Bahco shifters and the weaker limp wristed stuff that they stand above is that even after being hammered you can still use the nut to adjust it easily. And if all goes really pear shaped change the movable bits.But, the big difference is the jaw width. On the near magical 9031 a number that engineers know and love - the jaws can open further than your mother in law when in full rant. Truly epic and bloody useful especially when you are trying to nip up pipe fittings. Trust me,when you have humped a bag of tools up 50m in a machinery space at 65C heat only to find that you don't have a spanner quite big enough it can be a heart breaking experience. This is why marine engineers grap a shifter or two as soon as they walk our of a control room on rounds. That tool in your back pocket could save you a lot of sweat.Where I've found this to be idea is on hydraulic pipework and fridge systems to be honest. The size of nuts often used are just bigger than a standard Bahco and this little lifesaver goes wide enough to be properly useful.So, if you are looking for a shifter then look no further. There is no better on the market no matter how shiny or expensive (Snap-On which jams).

Really precise feel for an adjustable spanner
I bought this to replace a 200mm Draper adjustable spanner that (a) was becoming very difficult to adjust, and (b) despite indicating it could open just over 25mm, it in fact couldn't open as far as 25mm, which for domestic plumbing DIY was turning out to be a real pain.I bought this Bahco adjustable spanner based on the good reviews and the large jaw opening size, and I am super pleased with my purchase. The whole spanner feels very well made and solid. The jaws adjust extremely smoothly (though the screw operation is in the opposite to my old spanner). The jaws are quite long, and taper to a fairly slender point, which makes it really easy to fit onto small plumbing fittings, or where space is tight. Unlike my old spanner, the jaws don't work loose as you operate the spanner. The jaw opening width is also excellent, and it means I can now tackle most of my DIY plumbing jobs without having to resort to a larger spanner or grips.Overall, very pleased indeed.

Excellent medium-duty adjustable Wrench
You can refer to the customer photos I posted which illustrate some of the points I make. These are lightweight, well balanced and comfortable wrenches most suitable for electronic and plumbing applications (rather than heavy engineering). Their short 8" length limits the torque that may be applied - fortunate because I'm not at all sure they would stand up to much abuse without straining the jaw mechanism.Both the 9031 and the 9031T share the same body & handle but the 9031T (narrow jaw version) has one side of the jaws milled down which allows access into tight spaces or gripping thin nuts. Both offer an exceptionally wide opening of around 38mm. The two wrenches work well together in many circumstances where one threaded component has to be held in place whilst the other is used to loosen/tighten the other. That's the reason I bought both. The overall construction is very good - accurate forged parts which are correctly hardened and ground, and which fit together well. My one criticism is that as received there were many razor sharp corners left on the edges of the jaws, and also the inside faces were not as well finished as they might be. Both of these issues can be quickly dealt with by spending some time with oilstone to knock the sharp corners off and (for my 9031) remove some lumps and flatten the jaw faces. These jobs had already been done before I took the photos referred to above. This is worth doing if working on nice chromed plumbing parts otherwise these tools will scratch the finish all too easily (and you may also cut your fingers because they were that sharp). Treated well I would expect these tools to last a lifetime.

Worth every penny
You might think that at ยฃ20, it seems a little steep for an adjustable spanner. However these Bacho's are worth investing in. A joy to use, unlike other adjustable's I have purchased over the years these seem to work as they should with little or no movement from the jaws once set to the desired gap. The thumb turn screw easily adjust's the jaws to the desired size. Great design with the jaws, that allow them to get into the tightest of spaces. Use them for pluming all the time, used as a pair they are indispensable at tightening a multiple of joints. The 8" will do most common sizes and are probably the most flexible. The rubber around the handle is a nice touch and of high quality.

Reliable, easy to use tool
Great product from bahco, like all there tools. Some of the best adjustable wrenches out there. Easy to adjust , really comfortable in the hand (perfect weight) and have never let me down! Been using for two years now and still feel like brand new. Adjustable turner still really smooth and copes with all jobs. I recommend these to anyone looking for quality tools. Great value for money

Excellent, rigid secure movement in jaws
I have been using one of these Bacho wrenches for years.Benefits:These are highly engineered professional use wrenches. You really cannot compare to the budget versions that are abundant.Hardly any movement in the jaws so a nice tight grip. This is MAJOR plus point that differentiates this to other cheaper tools. The jaws are stiff and stay in place this minimised slippages and any consequential rounding of nuts and bolts. Do not underestimate the importance of this one fact!Narrow jaws, so you can get into the tightest of nuts, excellent for plumbing. Often in plumbing you may have a series of nuts against each other. The narrow jaws make it very easy to pin point the exact nut and not overlap on to the next.Really wide jaws, easily tighten bigger and smaller nuts no problem.Well balanced.Soft grip handle that fits perfectly in your hand.OUTSTANDING kit for the price it is A1!

Buy it!
As someone who works with tools on a daily basis, this adjustable wrench itโs top notch. Easily is my favorite go-to wrench now. The weight balance is perfect. The grip is amazing and resists oils and dirt. The lash between the worm drive is finely machined. Bahco engineers and machinist were firing on all cylinders when this was made.It gets used daily for hydraulic fittings, battery connections, basically any time I need a wrench, I grab this Bahco. It just works. And feels great in the hand.I will buy another 2 for the mobile tool kit and the personal truck tool kit.I also found out that Bahco makes these for SnapOn! SnapOn will rebrand them and request Bahco put nice polish on them with a red grip for them to sell at 5x the price, but they are 100% one and the same.I know in my picture itโs not a total apples to apples comparison as I have the SnapOn slim jaw version. But clearly, itโs a Bahco.Donโt hesitate, donโt think about. Just buy it. Trust me, you wonโt regret this

Great wrench, great quality
Expensive wrench, but worth having. Was disappointed to find out it was made in Spain and not in Sweden, jaws don't perfectly line up, but otherwise it is sturdy, smooth and precise. Has metric marking on one side and SAE on the other, rubber plastic compound grip is just right, I used it for mechanics and electrician, from large heavy nuts to knock-out punch draw stud duty, but also for large locknut on control panels and pipes, etc. For the same price I got a set of 4 Irwin Visegrip wrench (6", 8", 10", 12"), but this is the only wrench I carry in my pouch, since it's lighter and opens as big as a 12" wrench, but takes only the length of an 8" one. It won't replace a hefty 12" wrench, but sure will make your back pocket lighter when you're on the job site or service call.
