Irwin Vise-Grip The Original 7" Curved Jaw Locking Pliers - (PV7CR)

Self-energizing lower jaw provides 3X more gripping power than traditional locking pliers, with no slipping or stripping.

Curved jaw puts tremendous pressure on four points of any style nut or bolt head, making it perfect for any application that requires maximum torque. Constructed of high-grade heat-treated alloy steel for maximum toughness and durability. Hardened teeth are designed to grip from any angle. Hex key adjusting screw tightens to adjust pressure and draw materials together and provides a controlled release.
