Short Description

The Locking Plier 1641-7 (175 mm) is a professional-grade, medium-sized curved jaw locking tool designed for a wide range of gripping, clamping, and extraction tasks in automotive and industrial workshops.

Long Description

Forged from high-grade Chrome Vanadium (Cr-V) steel and scientifically heat-treated, the 1641-7 model offers the perfect balance between compact size and high clamping power. The 175-mm (7-inch) frame features a curved jaw profile with deep-cut hardened teeth, engineered to provide a secure three-point grip on round pipes, hexagonal nuts, and flat surfaces. An integrated wire cutter at the base of the jaws adds versatile functionality for cutting medium-tensile wires and small fasteners.

The tool utilizes a precision-machined adjustment screw at the handle base, allowing the user to calibrate the exact pressure required for the task. Once the handles are squeezed, the over-center locking mechanism maintains a high-torque hold without further hand pressure. To ensure safety and ease of use, it includes a guarded release trigger that allows for a quick and controlled opening. The entire body is finished with a durable nickel plating to protect against rust, corrosion, and welding spatter.

Why Choose This Product?

Choose the 1641-7 for its versatility and dependable strength. It is large enough to handle most common pipe and bolt sizes found in home and automotive repair, yet compact enough to fit into restricted areas. Because it locks firmly in place, it acts as a portable vice, freeing up the user's hands for other tasks like welding or drilling. Its heavy-duty Cr-V construction ensures the teeth remain sharp and the locking mechanism remains crisp over years of professional use.
