M4‑0.70 x 25mm Button Socket Cap Screw – Class 10.9, Black Oxide, ISO 7380

Designed for metric fastening applications that require extended length and reliable strength, this M4‑0.70 x 25mm button socket cap screw is manufactured from high‑strength Class 10.9 alloy steel and produced to ISO 7380 standards. The 25mm length provides deep thread engagement for secure fastening through thicker or multi‑component assemblies. Its low‑profile button head minimizes protrusion while maintaining a clean, finished appearance, and the internal hex drive allows precise torque control. Finished with a thermal black oxide coating, it offers reduced glare, mild corrosion resistance, and a uniform technical surface ideal for machinery, tooling, and precision mechanical applications.
