Stanley Curved Jaw Locking Pliers is great for securely gripping and applying torques to multiple surfaces like squares, round pipes, and hex bolts. The lower jaw features a pivot that allows it to align on the surface for maximum grip without stripping or slipping. This jaw mechanism grips tighter as more torque is applied. Stanley Curved Jaw Locking Plier is forged from high-grade alloy steel, which is heat-treated for long-lasting durability. Its chrome plating protects the plier from rust and corrosion.
