M4‑0.70 x 35mm Button Socket Cap Screw – Class 10.9, Zinc‑Baked (Cr+3), ISO 7380

Built for high‑strength metric fastening where extended reach is required, this M4‑0.70 x 35mm button socket cap screw is manufactured from heat‑treated Class 10.9 alloy steel and meets ISO 7380 specifications. The longer 35mm length supports deep thread engagement for secure fastening in thicker or multi‑layer assemblies, while the low‑profile button head provides a smooth, finished appearance in exposed or clearance‑restricted applications. Featuring an internal hex drive for precise 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—ideal for industrial, automotive, and mechanical use.
