IRWIN® Vise-Grip® Fast Release™ Curved Jaw Locking Pliers with a one-handed, triggerless release that is 2 times easier to open than traditional locking pliers. Anti-pinch, non-slip ProTouch™ grips provide comfort, control, and less hand fatigue. 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 from high-grade heat-treated alloy steel for maximum toughness and durability. Hardened teeth are designed to grip from any angle. Adjusting screw tightens to adjust pressure and draw materials together and provides a controlled release. Backed by the IRWIN VISE-GRIP Lifetime Guarantee.
