M12‑1.75 x 70mm Button Socket Cap Screw – Class 10.9, Black Oxide, ISO 7380

Engineered for heavy‑duty metric fastening where extended length and high tensile strength are required, this M12‑1.75 x 70mm button socket cap screw is manufactured from Class 10.9 alloy steel and produced to ISO 7380 standards. The 70mm length provides deep thread engagement for secure clamping in thick or multi‑layer assemblies, while the low‑profile button head helps reduce snagging and maintains a clean, finished appearance in exposed applications. 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 delivers a consistent technical finish suitable for industrial, structural, and machinery use.
