Irwin 4935578 Curved Jaw Locking Pliers 7 Inches

Product Description

The IRWIN INDUSTRIAL TOOL CO 4935578 is a 7-inch curved jaw locking plier designed for gripping, torquing, and clamping across multiple surface shapes. Built from high-grade alloy steel that is heat treated for toughness, this tool handles round pipes, square bolts, hex bolts, and irregular workpiece profiles. The self-engineering lower jaw pivot automatically aligns the jaw to the workpiece for maximum grip without slipping or stripping. A hex key adjusting screw lets the technician dial in the jaw opening precisely, tightening to draw material closer or loosening for a controlled release. The guarded release mechanism opens the jaw cleanly with minimal effort.

This locking plier is suited for plumbing, HVAC, and general mechanical service work where a technician needs secure, repeatable clamping force on fittings, fasteners, pipes, or damaged fastener heads. The curved jaw geometry accommodates round stock and pipe sections that straight-jaw models cannot seat cleanly. The jaw mechanism is designed to grip tighter as more torque is applied to the tool, reducing the need for heavy input pressure during stubborn fastener or fitting work. Sold in a package quantity of 5 units per order.

Compatibility

Designed as a general-purpose curved jaw locking plier for use across plumbing, HVAC, electrical, and mechanical service applications where clamping or torquing of varied workpiece shapes is required.

Installation Notes

This tool is intended for use by licensed trade professionals and experienced technicians. Before use on any pressurized system component, ensure the system is fully depressurized and de-energized per applicable safety codes. Inspect the jaw and pivot mechanism before each use and do not use the tool if the adjusting screw or release mechanism shows damage. Follow applicable OSHA hand tool safety guidelines when using locking pliers in confined or overhead work spaces.
