The Model 256 tool is designed for high-speed production applications, able to install up to 20 fasteners per minute. Slightly more swaging power than the Model 255 allows the 256 to install up to 3/8" steel Magna-Grip fasteners. The tool provides optimum stroke for one-cycle installations, and features an concentric (inline) pull piston and new fromt gland design, allowing for easy piston removal. The 256 is factory-tested for 2000 cycles, ensuring the tool's reliability, and plated piston rods extend seal life, adding to its durability. This proven production tool weighs only 11.1 pounds.
