Metric Socket Set Screws, Cup Point, Hex 0.9MM Drive, Stainless Steel A4 (316), M2 x .4 x 4MM
Screw Diameter x Thread Pitch: M2-0.40
|
This M2 x 0.4mm 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 0.9MM 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.
