M8‑1.25 x 50mm Button Socket Cap Screw – Class 10.9, Black Oxide, ISO 7380

Designed for metric fastening applications that require extended length and high tensile strength, this M8‑1.25 x 50mm button socket cap screw is manufactured from heat‑treated Class 10.9 alloy steel and produced to ISO 7380 standards. The 50mm length allows for deep thread engagement through thicker or multi‑component 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 enables 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.
