M12‑1.75 x 100mm Button Socket Cap Screw – Class 10.9, Black Oxide, ISO 7380

Engineered for heavy‑duty metric fastening applications requiring maximum reach and high mechanical strength, this M12‑1.75 x 100mm button socket cap screw is manufactured from Class 10.9 alloy steel and produced to ISO 7380 standards. The extended 100mm length allows for deep thread engagement through thick or multi‑layer assemblies, ensuring secure clamping and joint stability under load. Its low‑profile button head helps reduce 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, provides mild corrosion resistance, and delivers a consistent technical finish ideal for industrial, structural, and heavy‑machinery applications.
