M8‑1.25 x 80mm Button Socket Cap Screw – Class 10.9, Black Oxide, ISO 7380

Designed for metric fastening applications requiring extended reach and high tensile strength, 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 provides deep thread engagement through thick or multi‑layer assemblies, ensuring secure, load‑bearing performance. Its smooth, low‑profile button head minimizes snagging while maintaining a clean, finished appearance, and the internal hex drive supports precise torque application. Finished with a thermal black oxide coating, it offers reduced glare, mild corrosion resistance, and a durable technical finish suitable for industrial and mechanical use.
