M8‑1.25 x 65mm Button Socket Cap Screw – Class 10.9, Black Oxide, ISO 7380

Designed for metric fastening applications requiring extended length and high tensile strength, this M8‑1.25 x 65mm button socket cap screw is manufactured from heat‑treated Class 10.9 alloy steel and produced to ISO 7380 standards. The 65mm length provides deep thread engagement through thick or multi‑layer assemblies, ensuring secure, load‑bearing performance in demanding applications. Its smooth, low‑profile button head minimizes snagging while maintaining a clean, finished appearance, and the internal hex drive allows for 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.
