M4‑0.70 × 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 M4‑0.70 × 20 mm socket set screw with cup point is produced from A4 (316) stainless steel to provide excellent corrosion resistance and long‑term durability. The extended length offers increased thread engagement, while the cup point applies concentrated holding force into the mating surface to help resist loosening under vibration or light mechanical load. An internal hex socket drive allows accurate installation in recessed or space‑restricted assemblies. Commonly used in electronics, instrumentation, marine components, food processing equipment, and precision mechanical applications where secure fastening and corrosion resistance are critical.
