M3‑0.50 × 20 mm Socket Set Screw, Cup Point – Stainless Steel A4 (316), DIN 916

Manufactured to DIN 916 specifications for precision fastening in corrosive environments, the M3‑0.50 × 20 mm socket set screw with cup point is produced from A4 (316) stainless steel to deliver excellent corrosion resistance and long‑term durability. The extended length allows for increased thread engagement, while the cup point concentrates holding force into the mating surface to help resist loosening under vibration or light mechanical load. An internal hex socket drive enables accurate installation in recessed or space‑restricted assemblies. Commonly used in electronics, instrumentation, marine components, food processing equipment, and precision mechanical applications where compact size and corrosion resistance are critical.
