From the Manufacturer
Grip-Tite Super Wrenches - the wrenches with BITE! For the first time ever, all wrenches are not equal. Grip-Tite Super Wrenches remove rusted, damaged and severely rounded nuts and bolts with ease - where conventional wrenches just spin. Additionally, they hold and capture nuts and bolts in hard-to-reach places - no more banged knuckles or dropped fasteners (not magnetic). The secret to the bite is Grip-Tite's Patented Advanced Camming Technology, which grips the flats of the nut or bolt and holds tighter and tighter the harder you turn. Oh, and they work even better on good bolts and nuts. No-Hassle Lifetime Warranty.
