The 12mm Grub Screw (Allen Key Type) is a compact, headless fastener designed for reliable and flush-fit fastening in a wide range of mechanical and structural applications. Featuring a precision-machined internal hex drive, it allows strong tightening using a standard Allen key while remaining fully embedded within the component.

Made from treated, corrosion-resistant steel, this grub screw ensures excellent grip, stability, and long-term durability. Its strong thread profile offers superior holding power, making it ideal for use in clamps, collars, couplings, fixtures, Fessa tube systems, and other assemblies where space-saving and secure locking are required.

This screw is commonly used in orthopedic fixators, machinery, jigs, and alignment systems.
