M8‑1.25 x 45mm 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 45mm button socket cap screw is manufactured from heat‑treated Class 10.9 alloy steel and produced to ISO 7380 standards. The 45mm length provides deep thread engagement for secure fastening in thicker or multi‑component assemblies, ensuring reliable load performance. Its low‑profile button head helps reduce snagging while maintaining a clean, finished appearance in exposed installations. Featuring an internal hex drive for controlled torque application, it is finished with a thermal black oxide coating that reduces glare, offers mild corrosion resistance, and delivers a durable technical finish suitable for industrial and mechanical use.
