M4‑0.70 x 4mm Button Socket Cap Screw – Class 10.9, Zinc‑Baked (Cr+3), ISO 7380

Designed for precision metric fastening in low‑clearance applications, this M4‑0.70 x 4mm button socket cap screw is manufactured from heat‑treated Class 10.9 alloy steel and produced to ISO 7380 standards. The short 4mm length is ideal for shallow thread engagement where space is limited, while the smooth, low‑profile button head provides a clean, finished appearance. Featuring an internal hex drive for accurate torque application, 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—making it well suited for mechanical, automotive, and industrial assemblies.
