Designed for metric fastening applications requiring increased length and high mechanical strength, this M8‑1.25 x 30mm button socket cap screw is manufactured from heat‑treated Class 10.9 alloy steel and produced to ISO 7380 standards. The 30mm length provides deep thread engagement for secure fastening in machinery and structural assemblies, while the smooth, low‑profile button head helps reduce snagging and maintains a clean, finished appearance. Featuring an internal hex drive for precise 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.
