M8‑1.25 x 100mm Button Socket Cap Screw – Class 10.9, Zinc‑Baked (Cr+3), ISO 7380

Designed for high‑strength metric fastening applications requiring maximum length and corrosion protection, this M8‑1.25 x 100mm button socket cap screw is manufactured from heat‑treated Class 10.9 alloy steel and produced to ISO 7380 standards. The extended 100mm length allows for deep thread engagement through thick or multi‑layer assemblies, ensuring secure, load‑bearing performance in demanding conditions. Its smooth, low‑profile button head delivers a clean, finished appearance in exposed or clearance‑restricted applications, while the internal hex drive supports precise torque application. Finished with a zinc‑baked coating and trivalent chromium (Cr+3) passivation, it enhances corrosion resistance and reduces the risk of hydrogen embrittlement—making it well suited for industrial, automotive, and mechanical use.
