Hex Socket Set Screws, also known as grub screws or hollow screws, are essential fasteners used in various industrial applications to secure objects within or against another object without protruding. These screws feature a headless design with an internal hexagonal drive, allowing for a flush fit that is ideal for applications requiring a smooth surface. Available in a range of materials including steel, stainless steel, titanium, brass, and aluminum, they are designed to suit different environmental conditions and mechanical requirements. The screws come in multiple tip shapes such as flat tip, cone point, cup point, dog point, and more, each providing unique holding characteristics and suited for specific uses. Surface treatments like black oxide, nickel plating, chrome plating, and trivalent chromate enhance their durability and resistance to corrosion. These versatile screws are commonly used in securing pulleys, collars, and gears to shafts, ensuring reliable performance in machinery and equipment.
