M8‑1.25 x 100mm Button Socket Cap Screw – Class 10.9, Black Oxide, ISO 7380

Designed for metric fastening applications requiring maximum length and high tensile strength, 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 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 delivers reduced glare, mild corrosion resistance, and a durable technical finish suitable for industrial and mechanical use.
