Product Introduction
Engineered for superior comfort, high torque, and safety, our Curved Jaw Locking Pliers with Ergonomic Plastic Handle (W29111 – W29113 Series) combine heavy-duty industrial clamping performance with non-slip operator comfort. Stamped from high-strength alloy steel, the body provides maximum structural rigidity under extreme load. The drop-forged alloy steel jaws undergo whole-tool heat treatment for maximum hardness and long-lasting tooth durability. The curved jaw wraps firmly around round pipes, hex nuts, and irregular workpieces, while the integrated induction-hardened blade cuts soft to medium-hard wires. Designed with ergonomic dual-material plastic grips that cushion the hand and reduce fatigue during repetitive use. Equipped with a precision tail bolt to calibrate jaw opening and clamping tension up to 1135 kg, as well as a guarded safety release lever (anti-pinch design) that buffers handle snap-back during unlocking. Available in 140mm (5″), 180mm (7″), and 220mm (10″) sizes.
