Irwin 4935576 10 Inch Curved Jaw Locking Pliers 5 Pack

Product Description

The IRWIN INDUSTRIAL TOOL CO 4935576 is a 10 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, these pliers deliver reliable holding force on round pipes, square bolts, hex fasteners, and irregular workpieces. The self-engineering lower jaw pivot automatically aligns the jaw to the workpiece, maximizing grip contact without slipping or stripping fasteners. A hex key adjusting screw controls jaw opening width, allowing the technician to draw material tighter or release with controlled, predictable action. Licensed plumbers, HVAC technicians, pipefitters, and general trade professionals keep these in regular rotation for field work and shop use. Sold as a pack of 5 units.

The 4935576 is suited for residential and commercial trade applications where a single tool must handle varied fastener geometry and pipe sizes. The curved jaw profile makes it effective on round stock and pipe work, a common task in plumbing rough-in, HVAC refrigerant line work, and mechanical service. The guarded release mechanism allows jaw opening without fumbling, which matters during overhead or confined-space work. Each pack includes 5 individual pliers, making this a practical buy for stocking a service truck, outfitting a crew, or keeping spares on the bench.

Installation Notes

Locking pliers are a hand tool requiring no installation, but proper use practices apply. Adjust jaw width with the hex key screw before clamping to avoid over-stressing the adjustment mechanism. When working on pressurized pipe systems, always depressurize and isolate the line before applying any clamping tool. Follow applicable trade codes and employer safety guidelines when using locking pliers on electrical conduit, gas lines, or refrigerant tubing.
