M6‑1.00 x 70mm 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 M6‑1.00 x 70mm button socket cap screw is manufactured from heat‑treated Class 10.9 alloy steel and produced to ISO 7380 standards. The 70mm length provides deep thread engagement for secure fastening through thick or stacked assemblies, supporting strong, load‑bearing joints. Its low‑profile button head offers a smooth, finished appearance while minimizing snag points in exposed installations, and the internal hex drive allows for 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 precision mechanical applications.
