    • Klein is what snap-on used to be - quality tools that don't let you down
Style: Extra-Wide Jaw, 8-Inch
This is a relatively heavy, well made, adjustable wrench. It lacks a positional lock but otherwise does everything you can reasonably expect from an adjustable wrench. The manufacturing precision is really what set this tool apart. Too often I find cheap wrenches which after a few uses the jaw faces are no longer parallel. Or there is too much slack and wobble in the sliding jaw. While I have owned wrenches which were even tighter in terms of precision movement, they cost more than twice as much (and are increasingly hard to find these days). The width of the fully opened jaw is also a stand-out feature - certainly wider than any 8 inch wrench in my toolbox. Overall the spanner feels 'chunky' and solid in my hand, with an excellent grip. I should add, I 'found' this brand after watching a youtube video from project farm - this youtuber reviews and tests (to destruction) a wide variety of tools and glues etc.. Klein came out as his preferred choice for people on a budget (aka me). ... show more

    • Ol' Reliable
Style: Extra-Wide Jaw, 8-Inch
Good value for the price. You can definitely find more refined adjustables like the bahco or the channel lock, any Japanese adjustable, or a pliers wrench. They are all made in Spain but the form of the klein (I bought the regular wide mouth and the ground-down thin jaw) is most reminiscent of classic adjustable wrenches, and handles like an older wrench. Is it my favorite wrench to use at work? Maybe, but it's the one I don't worry about the chrome finish coming off, or slipping off a fastener or ruining the adjustment mechanism. Comfort of use and reliability make this my go-to for anything 3/8 " and larger. ... show more

    • Very wide jaws
Style: Extra-Wide Jaw, 8-Inch
This is the best adjustable wrench made. It just extremely wide and is very smooth when operating. I have had one for 10 years with nowhere and I’m hard on tools. Worth the extra money.

    • Beware of receiving someone's return at a new price
Style: Extra-Wide Jaw, 8-Inch
Looked like somebody's "try before you buy" item that they didn't want and returned it. Package obviously opened before I received it. Had dents and discoloration on the metal. Jaw adjusting screw was more loose than the same item I looked at in Home Depot. Priced the same as Home Depot's new piece. Otherwise okay. Serves the purpose. ... show more

    • Well made
Style: Extra-Wide Jaw, 8-Inch
This adjustable wrench is my favorite wrench in my tool bag. It's well made and has a nice feel to it. The jaw is very smooth when adjusting as well. Some people have rated this wrench lower due to the Spanish steel it's made from, claiming it's soft.. They must have forgotten that Spanish steel was highly sought after for sword making due to its perfections. The jaw does not move when applying force, it stays in place so rounding off a nut or bolt isn't going to happen unless you are careless. ... show more
