IRWINIndustrial Tools 2078605 10-Inch SAE Quick Adjusting Wrench

Five stars plus!As another reviewer noted, "No more fumbling with those thumb screws that constantly drift off size."That's the long and short of it. Also no need to figure out which way you're holding the wrench - i.e. which way to turn the thumbscrew. A significant improvement that makes an essential tool more of a helper and less of a hassle. Everyone on the job who sees mine wants one, so it's not just me.NB: There's this SAE model and also a metric model. It's a weird thought that this could matter in an adjustable wrench, but the pre-set adjustment notches make it true. So if you're doing all SAE like me, it's this one; if you're doing metric, search "Irwin Quick Adjusting Metric Wrench".And there are varying lengths for each, and a package with both SAE and metric, blah blah blah.

Quick one hand adjustment. Better fit on nuts and bolts than other adjustable wrenches

a gift

This is a very handy crescent, I work in Colorado on a oil-rig and constantly use a crescent throughout the day. This is the best i have come across yet, its tough and can be adjusted much quicker than the traditional crescent wrench. I highly recommend this to anybody looking for a great 10inch crescent.

Product works as described.

These wrenches are very good; however, it's important to note that---unlike a traditional adjustable wrench---the jaws are NOT infinitely adjustable within their 1-1/4" range of motion. Instead their range is divided into pre-defined 1/16" notches. This system accounts for the wrench's excellent holding properties on US/English objects. But, it means that the wrench will NOT hold tightly on metric sized objects.

Irwin has come up with what is truly the best designed adjustable wrench ever. First off fit and finish are superb, justifying its higher price. What really sets it apart is the locking mechanism they have come up with. Little teeth lock the settings in place and with the release of the spring switch you can easily change to another width and it stays put. Also has a quick size adjustment where you fully open the jaws, then squeeze fit to the nut, and presto its set and stays there. No more fumbling with those silly thumb screws that constantly drift off size. Another plus is the rubberized handle that is both comfortable as well as functional with its firm grip. This will definitely be the one you grab to use.
