  • 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.

  • 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

  • Love it
Style: Extra-Wide Jaw, 8-Inch
As an apprentice I was given many tools to start in the world of electrical apprenticeship from family. Quickly decided I needed a better wrench and as the best tools they gave me were Klein I started looking. This wrench has far better reviews than most so I spent the $ and bought it. One of the best decisions I have made! Don't hesitate to get it. Truly well worth the $ ... show more

  • 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
