M4‑0.70 × 16 mm Socket Set Screw, Cup Point – Stainless Steel A4 (316)

Designed for fastening applications that require extended thread engagement in corrosive environments, the M4‑0.70 × 16 mm socket set screw with cup point is manufactured from A4 (316) stainless steel for excellent corrosion resistance and long‑term durability. The longer length provides increased holding depth, while the cup point concentrates force into the mating surface to help prevent loosening under vibration or light mechanical load. An internal hex socket drive allows precise installation in recessed or space‑restricted assemblies. Commonly used in electronics, instrumentation, marine components, food processing equipment, and precision mechanical assemblies where reliable fastening and corrosion resistance are essential.
