M4‑0.70 x 16mm Button Socket Cap Screw – A4 Stainless Steel (316)

This M4‑0.70 x 16mm button socket cap screw is manufactured from A4 (316) stainless steel for superior corrosion resistance in marine, chemical, and outdoor environments. The 16mm length provides deeper thread engagement for secure fastening in thicker or multi‑layer assemblies, while the low‑profile button head delivers a smooth, professional appearance in visible or clearance‑restricted applications. Featuring an internal hex drive, it is ideal for metric fastening where strength, durability, and long‑term corrosion resistance are critical.
