These new Power Grip Jaws replace and outperform pliers, channel locks, pipe wrenches and vise-type tools. Full 360 degree rotating/self adjusting ratcheting head operates at any angle on pipes, fittings, bolts and nuts of all kinds. Power Grip Jaws are excellent for rusted and frozen bolts as well as "rounded" off heads. The harder you press, the tighter it grips. May also be used for tie rod adjusters.
