M4‑0.70 x 35mm Button Socket Cap Screw – Class 10.9, Black Oxide, ISO 7380

Engineered for metric fastening applications requiring extended length and high mechanical strength, this M4‑0.70 x 35mm button socket cap screw is manufactured from Class 10.9 alloy steel and produced to ISO 7380 standards. The 35mm length allows for deep thread engagement through thicker or multi‑layer assemblies, improving joint security and load distribution. Its low‑profile button head offers a smooth, streamlined appearance in exposed or clearance‑restricted installations, while the internal hex drive enables precise torque control. Finished with a thermal black oxide coating, it provides reduced glare, mild corrosion resistance, and a consistent technical finish ideal for machinery, tooling, and precision mechanical assemblies.
