The DONGCHENG HD071604 10 Inch (about 250 mm) Straight Jaw Locking Pliers are made for mechanics, welders, fabricators, and maintenance professionals who need a strong, hands-free clamp on bigger work. The straight jaws sit flat against the work, which gives an even hold on sheet metal, flat bar, square stock, and panels. The adjustable screw lets you set the jaw opening to the part, and once closed, the release lever locks the pliers in place so the grip stays tight without constant hand pressure. The 250 mm handles give good leverage and a wide jaw capacity.
