Replacement Part, 5-Pc Spring Set, for 4LN®/4LW®/4SP™/4WR® Locking Tools

Self-energizing lower jaw provides 3x more gripping power than traditional locking pliers with no slipping or stripping. Provides maximum torque without requiring heavy input pressure as jaw mechanism naturally grips tighter as more torque is applied to the tool. One-handed, triggerless release is 2x easier to open than traditional locking pliers. Anti-pinch, non-slip 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 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.
