    • Three 4-inch adjustable wrenches
Style: Dipped Handle, 4-Inch
I bought 3 different 4-inch (nominal) adjustable wrenches for comparison: The Klein D506-4, the Channellock 804 and the Bahco 8069 RC US. I'll review them together. An older review, by another customer, of 8" wrenches may be of interest https://www.amazon.com/gp/customer-reviews/R1VXP5HDPQ5FER . All three wrenches are made in Spain, and all are longer than 4" (4.3 for the Bahco, 4.5 for the Channellock and Klein.) And despite various information on their packages and on the Amazon listings, they all open to 9/16" (14mm.) They all have inch and metric scales on the jaws, but only the Channellock has a mark at 9/16; none have a mark at 14mm. The Channellock and the Klein are clearly related, having the same jaw, screw and pin in the familiar US style. The Channellock is stamped with the brand, but the raised Klein name is in the forging. The Klein also has a round hanging hole instead of the Spanish-style square hole. The Bahco (nee Sandvic, now part of Snap-on's Williams division) is quite different, having the traditional Swedish buttressed jaws that may be stronger but are a little bulky. Note that this "US" version has the familiar RH thread; LH is the norm in Sweden. All three have excellent quality, with little play in their slides and screws, good machining and parallelness. The Klein is only available with a vinyl grip and the Bahco, while beautiful, is stronger than I need a 4" wrench to be, so the Channellock gets my nod. Barely. ... show more

    • The Best Adjustable Wrench I've Ever Used
Style: Dipped Handle, 8-Inch
I was watching Project Farm's review of adjustable wrenches, and I saw that the Klein wrenches were a top pick. Amazon didn't have the exact model that he tested, but I felt like I could trust any of these Klein. I ended up picking this one because my use is mostly for theatrical/houses of worship and the bolts/nuts I need to turn are all under 1 inch in diameter. I loved the plastic dipped handle, and the build quality is top notch. As a reference, I've only used cheap Chinese wrenches from the red and blue discount tool store. This is definitely one of those buy once, cry once kind of purchases. But it is totally worth it in my opinion. ... show more

    • Buy once, cry once
Style: Dipped Handle, 8-Inch
This adjustable wrench only appears expensive because you haven't used it yet. It has a beautiful weight in the hand. The machining is detailed and precise, and my sense is that I've made a purchase that will last well past my lifetime. I smile every time I use it. This is my second purchase from Klein Tools, and although I prefer USA made, they seem to have sufficiently high quality standards to wow me. This feels like the 8" wrench equivalent of a 4-ply cashmere sweater. (Very nice.) ... show more

    • Well made
Style: Dipped Handle, 8-Inch
Well made. Jaw has very little lateral movement and stays adjusted. Very little slop on adjustment knob, just enough not to jam the jaw. Price should be better to keep a working man happy buying tools.

    • Sweet wrench but a bit small
Style: Dipped Handle, 4-Inch
Honestly one of the best adjustable wrenches I’ve ever owned but when I bought it I neglected to read the reviews and it’s teeny. It’s a great wrench though I like the tool, it’s excellent quality and lives up to the quality I expect from Klein tools. I thought about returning it but it’s gotten daily use in my tool pouch so now it has a permanent home there, if I lose it I wouldn’t hesitate to buy another. Also Klein tools people if you’re reading this sponsor me I will shill your wonderful products because they are ACTUALLY the best tools in my bag ... show more
