The Powerbuilt 10 piece Metric Combination Wrench Set is as pretty to look at as it is strong. Each wrench is constructed from tough chrome vanadium steel that resists wear better than carbon steel. And they're mirror-polished to a smooth flawless finish, making these end wrenches almost too pretty to use. But use them you should, and with beveled flats for easy mating to bolts and a 15 degree knuckle offset, consider these your new go-to combination wrenches. The box ends also features Z-Drive design that contacts the flat walls of fasteners for better grip and less chance of rounding. The set includes metric wrenches from 10mm through 19mm to cover the most common nut and bolt sizes. There's even a vinyl roll pouch included to keep these beauties safe and clean between uses.
