M12‑1.50 x 55mm Button Socket Cap Screw – Class 10.9, Zinc‑Baked (Cr+3), ISO 7380

Designed for high‑strength metric fastening applications requiring extended length and dependable corrosion protection, this M12‑1.75 x 55mm button socket cap screw is manufactured from heat‑treated Class 10.9 alloy steel and produced to ISO 7380 standards. The 55mm length provides deep thread engagement for secure fastening in thick or multi‑component assemblies, ensuring reliable load‑bearing performance. Its smooth, low‑profile button head delivers a clean, finished appearance in exposed or clearance‑restricted applications, while the internal hex drive enables precise torque control. Finished with a zinc‑baked coating and trivalent chromium (Cr+3) passivation, it enhances corrosion resistance and reduces the risk of hydrogen embrittlement—making it well suited for industrial, automotive, and mechanical use.
