M8‑1.25 x 70mm Button Socket Cap Screw – Class 10.9, Zinc‑Baked (Cr+3), ISO 7380

Designed for high‑strength metric fastening applications requiring extended length and enhanced corrosion protection, this M8‑1.25 x 70mm button socket cap screw is manufactured from heat‑treated Class 10.9 alloy steel and produced to ISO 7380 standards. The 70mm length allows for deep thread engagement through thick or multi‑layer assemblies, ensuring secure, load‑bearing performance. Its smooth, low‑profile button head maintains a clean, finished appearance in exposed or clearance‑restricted applications, while the internal hex drive enables precise torque application. Finished with a zinc‑baked coating and trivalent chromium (Cr+3) passivation, it offers improved corrosion resistance and reduced risk of hydrogen embrittlement—making it well suited for industrial, automotive, and mechanical use.
