The DONGCHENG HD071610 10 Inch (about 250 mm) CR-V Curved Jaw Locking Pliers are made for mechanics, welders, fabricators, plumbers, and maintenance professionals who need a strong, hands-free clamp on bigger work. The body is made from chrome vanadium (CR-V) steel, which is known for strength and wear resistance. The curved jaws wrap around round, hex, and irregular shapes, and the adjustable screw lets you set the jaw opening to the part. Once closed, the release lever locks the pliers in place, so the grip stays tight without constant hand pressure.
