JAKOB clamping screws were conceived right from the beginning for highest demands and maximum workpiece weights with best possible operational reliability. The user can choose between single- and double-acting designs. The screws are equally suitable for external and internal clamping. JAKOB clamping screws are used in face plates or clamping discs on vertical, horizontal, center, facing and roll turning lathe, in grinding and special machines.
All components are made from hardened steel and produced with high precision which guarantees the user a robust and reliable clamping element.
