M12‑1.50 x 45mm Button Socket Cap Screw – Class 10.9, Zinc‑Baked (Cr+3), ISO 7380

Designed for high‑strength metric fastening applications requiring reliable clamping and corrosion protection, this M12‑1.75 x 45mm button socket cap screw is manufactured from heat‑treated Class 10.9 alloy steel and produced to ISO 7380 standards. The 45mm length provides strong thread engagement for secure fastening in structural and heavy mechanical assemblies, while the low‑profile button head delivers a smooth, finished appearance in exposed installations. 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 well suited for industrial, automotive, and machinery applications.
