Grub Screws
Grub Screws (Socket Set Screws)
Grub Screws—also known as Socket Set Screws—are headless fasteners designed to sit flush within or below the surface of a component. Used primarily for securing an object within or against another object, such as fixing a gear or pulley to a shaft, they provide a strong, reliable hold without protruding above the surface.
These screws feature a hex socket drive for easy and secure installation using an Allen key, ensuring precise torque control and reducing the risk of slippage or stripping. Grub screws are available in a variety of thread types and sizes to suit a broad range of mechanical and industrial applications.
Commonly used in assemblies where space is limited or a smooth external profile is needed, grub screws are ideal for machinery, electronics, automotive, and general engineering tasks. Their discreet profile and high holding power make them essential for precision fastening in confined or hidden locations.
