M8‑1.25 x 80mm Button Socket Cap Screw – Class 10.9, Zinc‑Baked (Cr+3), ISO 7380

Engineered for high‑strength metric fastening applications that require extended length and reliable corrosion protection, this M8‑1.25 x 80mm button socket cap screw is manufactured from heat‑treated Class 10.9 alloy steel and produced to ISO 7380 standards. The 80mm length allows for deep thread engagement through thick or multi‑component assemblies, ensuring secure, load‑bearing performance. Its smooth, low‑profile button head delivers 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 enhances corrosion resistance and reduces the risk of hydrogen embrittlement—making it well suited for industrial, automotive, and mechanical use.
