M12‑1.75 x 55mm 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 55mm button socket cap screw is manufactured from Class 10.9 alloy steel and produced to ISO 7380 standards. The 55mm length provides deep thread engagement for secure clamping in thick or multi‑component assemblies, while the low‑profile button head helps maintain a streamlined appearance and reduces snagging 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 delivers a consistent technical finish suitable for industrial, structural, and machinery use.
