M6‑1.00 x 30mm Button Socket Cap Screw – Class 10.9, Black Oxide, ISO 7380

Engineered for metric fastening applications requiring extended length and high mechanical strength, this M6‑1.00 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 through thicker components or stacked assemblies, enhancing joint stability under load. Its low‑profile button head offers a smooth, finished appearance while minimizing snag points, and the internal hex drive allows for controlled torque application. Finished with a thermal black oxide coating, it delivers reduced glare, mild corrosion resistance, and a consistent technical finish suitable for industrial and precision mechanical use.
