M3‑0.50 × 3 mm Socket Set Screw, Cup Point – Stainless Steel A4 (316)

Designed for precision fastening in compact assemblies, the M3‑0.50 × 3 mm socket set screw with cup point is manufactured from A4 (316) stainless steel to provide excellent corrosion resistance and long‑term durability. The cup point delivers reliable holding power by gripping the mating surface, helping prevent loosening under vibration or light load. An internal hex socket drive allows accurate installation in small, recessed, or space‑restricted applications. Commonly used in electronics, instrumentation, marine components, food processing equipment, and precision mechanical assemblies where corrosion resistance and secure fastening are essential.
