Grub Screw
Grub Screws (Socket Set Screws)
Our Grub Screws, technically known as Socket Set Screws, are headless fasteners designed to secure an object within or against another object. Commonly used to secure pulleys, gears, and shaft collars to shafts, they sit flush with or below the surface of the material for a streamlined, safe finish. We offer various point styles including Cup Point (standard grip), Cone Point (permanent setting), and Flat Point (frequent adjustment) to suit every mechanical requirement.
