This M5‑0.80 x 45mm button socket cap screw is manufactured from A4 (316) stainless steel to provide exceptional corrosion resistance in marine, chemical, and outdoor environments. The extended 45mm length allows for deep thread engagement and secure fastening in thicker or multi‑layer assemblies, while the low‑profile button head offers a smooth, professional appearance in visible or clearance‑restricted applications. Featuring an internal hex drive, it is ideal for precision metric fastening where strength, durability, and long‑term corrosion resistance are required.
