M8‑1.25 x 50mm Button Socket Cap Screw – Class 10.9, Zinc‑Baked (Cr+3), ISO 7380

Designed for high‑strength metric fastening where extended length and reliable corrosion protection are required, this M8‑1.25 x 50mm button socket cap screw is manufactured from heat‑treated Class 10.9 alloy steel and produced to ISO 7380 standards. The 50mm length provides deep thread engagement for secure fastening through thicker or multi‑component assemblies, ensuring dependable load performance. Its smooth, low‑profile button head delivers a clean, finished appearance in exposed or clearance‑restricted applications, while the internal hex drive allows 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.
