Tekton long nose locking pliers are designed to reach into tight spaces. The long, tapered straight section clamps flat stock, L-angle, and sheet metal in position for welding or assembly. Its shallow, regularly spaced teeth provide an evenly distributed grip on smooth, flat surfaces. The curved section locks onto smaller hex, round, and square-shaped pieces with the aggressive bite of deep, sharp teeth. Easily set, release, and reposition the clamp with one hand and with more control than a traditional pinch-style lever. Get extra leverage and fine-tune your clamping force by inserting a screwdriver or hex key into the through-hole to create a T-handle. The jaws are made from 4140 chromium molybdenum steel, an alloy that offers toughness, machinability, and corrosion resistance. The teeth are hardened to 45-50 HRC and should not chip or strip even on fasteners up to Grade 8 or Class 12.9. The pliers have a durable, nickel-plated finish that protects against corrosion.
