A BSF (British Standard Fine) grub screw, also known as a socket set screw, is a headless, fully threaded imperial fastener used to secure components—such as gears, pulleys, or collars—onto a shaft. It features the BSF fine thread pitch, which is closer together than the coarse BSW (British Standard Whitworth) thread.
