Crimping pliers for micro pins. The parallel crimping performance meets the high standards of small connectors. Consistently high crimp quality is ensured by precision tools and a force-locking mechanism. The tools are factory calibrated for precision. Optimal power transmission is achieved through a lever for fatigue-free operation. The capacity includes semicircles, square millimeters, square drives, step squares, triangles, as well as clamping widths for hexagonal, round, and square shapes.
