Short Description

The Locking Curved Jaw Plier 1641-10/1641N-10 (250 mm) is a heavy-duty, industrial-grade locking tool designed for maximum clamping force and high-torque gripping on pipes, bolts, and irregular-shaped fasteners.

Long Description

Forged from premium Chrome Vanadium (Cr-V) steel and scientifically heat-treated, the 1641-10 series is built for the most demanding mechanical and industrial tasks. The 250-mm (10-inch) frame provides the necessary leverage to apply extreme pressure, making it an ideal choice for extracting seized or rounded-off bolts. The curved jaw design is specifically engineered to wrap around round objects, providing a secure three-point contact that prevents slipping even under high torque. The 1641N-10 variant includes further optimized tooth geometry for an even more aggressive bite on hardened materials.

This tool features a precision-machined adjustment screw at the base of the handle to calibrate the jaw opening and clamping pressure. An integrated wire cutter at the base of the jaws allows for the cutting of medium-tensile wires and small fasteners without switching tools. The over-center locking mechanism ensures the plier stays firmly locked in place until the guarded release trigger is activated. The entire tool is finished with a professional nickel-plated coating to provide superior resistance against rust, corrosion, and welding spatter.

Why Choose This Product?

Choose the 1641-10/1641N-10 for its massive gripping power and "portable vice" functionality. The 10-inch handle length acts as a powerful force multiplier, allowing you to lock onto workpieces with immense stability. It is the definitive choice for professional mechanics, plumbers, and welders who need a reliable tool that can hold, twist, and pull without releasing until intended. Its heavy-duty Cr-V construction and induction-hardened teeth ensure a long service life even in the harshest workshop environments.
