Crimp insulated and non-insulated solderless terminals and connectors for 10 to 20 AWG wires. The pliers are constructed entirely of premium Japanese forged high-carbon steel and underwent state of the art heat treating process. Combined with our superior bevel design, our pliers stay sharp over time. Our high leverage mechanism enables you to use 50% less effort than conventional pliers. The flat and round serrated gripping jaws gives you the ultimate grip on both flat and round objects. Minimum gap between flat jaw tips lets you grip onto even thin sheets. A thin profile makes these pliers lighter and more agile especially in tight spots. The Klinge High Leverage Combination Pliers meet ASME B107.11 standards.
