M12‑1.75 x 80mm Button Socket Cap Screw – Class 10.9, Black Oxide, ISO 7380

Designed for heavy‑duty metric fastening applications requiring extended length and high strength, this M12‑1.75 x 80mm button socket cap screw is manufactured from Class 10.9 alloy steel and produced to ISO 7380 standards. The 80mm length allows for deep thread engagement through thick or multi‑layer assemblies, ensuring secure clamping and reliable load performance. Its low‑profile button head reduces snagging while maintaining a clean, finished appearance in exposed installations. Featuring an internal hex drive for controlled torque application, it is finished with a thermal black oxide coating that reduces glare, offers mild corrosion resistance, and provides a consistent technical finish suitable for industrial, structural, and machinery applications.
