Halder Tension Levers | Adjustable Clamping Levers | DIN Standards

Halder star grips, also known as star knobs or star grip screws, are hand-operated fastening components designed for quick, tool-free tightening and adjustment in fixtures, jigs, machine guards, and industrial assemblies. Their star-shaped profile provides a comfortable, secure grip, allowing operators to apply consistent hand-tightening force without the need for a wrench or driver.
