This M8 x 1.25mm cup point socket set screw is manufactured from A4 (316) stainless steel, delivering superior corrosion resistance in marine, coastal, chemical processing, and other demanding environments where standard 18-8 stainless falls short. The cup point design features a shallow circular recess that bites into the mating surface, creating a reliable holding connection that resists vibration and rotational loosening. Driven with a 4MM hex socket key, these headless fasteners sit flush or below the surface for clean, snag-free assemblies. Ideal for securing collars, pulleys, gears, and shafts in applications exposed to saltwater, harsh chemicals, or high-humidity conditions.
