Locking pliers fix their jaws like a vise onto objects and materials, providing a secure hold to grip, turn, and clamp. Their adjustment screw fine tunes the jaws' clamping pressure, and their release trigger quickly unlocks the jaws. Also known as vice grips, locking pliers are an alternative to pipe wrenches and clamps. They are commonly used to turn frozen bolts and position panels or framing in welding, metalworking, and construction applications.
