M4‑0.70 x 12mm Button Socket Cap Screw – Class 10.9, Zinc‑Baked (Cr+3), ISO 7380

Designed for high‑strength metric fastening with added length, this M4‑0.70 x 12mm button socket cap screw is manufactured from heat‑treated Class 10.9 alloy steel and produced to ISO 7380 standards. The 12mm length provides increased thread engagement for secure clamping in mechanical and machinery assemblies, while the smooth, low‑profile button head maintains a clean, finished appearance in exposed 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, making it ideal for industrial, automotive, and mechanical use.
