M6‑1.00 x 65mm Button Socket Cap Screw – Class 10.9, Black Oxide, ISO 7380

Designed for metric fastening applications that require extra reach and high tensile strength, this M6‑1.00 x 65mm button socket cap screw is manufactured from heat‑treated Class 10.9 alloy steel and produced to ISO 7380 standards. The extended 65mm length allows for deep thread engagement through thick or multi‑layer assemblies, supporting secure, load‑bearing joints. Its smooth, low‑profile button head helps reduce snagging and maintains a clean, finished appearance in exposed installations, while the internal hex drive enables precise torque application. Finished with a thermal black oxide coating, it provides reduced glare, mild corrosion resistance, and a durable technical finish suitable for industrial and precision mechanical applications.
