M4‑0.70 x 6mm Button Socket Cap Screw – Class 10.9, Zinc‑Baked (Cr+3), ISO 7380

Designed for compact, high‑strength metric fastening, this M4‑0.70 x 6mm button socket cap screw is manufactured from heat‑treated Class 10.9 alloy steel and produced to ISO 7380 standards. The short 6mm length is ideal for shallow thread engagement and tight assemblies, while the smooth, low‑profile button head provides a clean, finished appearance in visible or clearance‑restricted applications. Featuring an internal hex drive for precise torque control, it is finished with a zinc‑baked coating and trivalent chromium (Cr+3) passivation to enhance corrosion resistance and reduce the risk of hydrogen embrittlement—well suited for mechanical, automotive, and industrial use.
