2507 duplex stainless steel hex socket cup point set screws are compact, headless fasteners designed for secure positioning, locking, and adjustment in demanding assemblies. With a fully threaded body, an internal hex drive, and a concave cup point, this fastener can hold shafts, collars, gears, pulleys, valve components, and precision machinery parts without adding external head height. For marine, chemical, offshore, pump, valve, and high-chloride environments, 2507 duplex stainless steel offers a useful balance of high mechanical strength and excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. Compared with standard 304 or 316 stainless steel, 2507 is often selected when the application needs stronger clamping performance and longer service life in aggressive media. Product Overview This product is a 2507 duplex stainless steel internal hex cup point set screw, also known as a hex socket grub screw or socket set screw. The screw is installed with an Allen key through the internal hex socket. The cup point creates a localized holding contact on the mating part, helping the screw resist loosening under vibration and repeated adjustment. Why Choose 2507 Duplex Stainless Steel? 2507 duplex stainless steel combines austenitic and ferritic microstructures, giving it both high strength and strong corrosion resistance. The alloy is especially suitable for chloride-bearing environments where conventional stainless grades may suffer from localized corrosion. For set screws, this matters because the part is small but often works in a critical locking position. If the screw corrodes, seizes, or loses holding force, the entire assembly can become difficult to service. 2507 helps reduce that risk in seawater equipment, desalination systems, chemical processing lines, and other harsh-duty applications. Hex Socket and Cup Point Design The internal hex socket allows the screw to be installed flush or below the surface of the assembly. This is useful where a…
