Nut runner pull clamps provide quick and secure fastening and are ideal for 5-axis machining and workpiece machining on a horizontal machining center. When a workpiece is loaded onto the clamp and positioned, the clamping screw compressed in the clamp body fits by spring pressure into the tapped hole in the workpiece. Turning the hex head located on the side of the clamp rotates the screw and pulls down the workpiece. The hex head can be turned manually or operated with an impact wrench. The hex head makes it ideal for use with a nut runner on automated production lines.
