M6‑1.00 x 80mm Button Socket Cap Screw – Class 10.9, Black Oxide, ISO 7380

Designed for metric fastening applications requiring maximum length and high mechanical strength, this M6‑1.00 x 80mm button socket cap screw is manufactured from heat‑treated Class 10.9 alloy steel and produced to ISO 7380 standards. The extended 80mm length allows for deep thread engagement through thick or multi‑layer assemblies, ensuring strong, load‑bearing joints. Its smooth, low‑profile button head helps reduce snagging while maintaining a clean, finished appearance in exposed installations. 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 precision mechanical applications.
