M3‑0.50 x 8mm Button Socket Cap Screw – Class 10.9, Zinc‑Baked (Cr+3), ISO 7380

Engineered for high‑strength metric fastening with added thread engagement, this M3‑0.50 x 8mm button socket cap screw is manufactured from heat‑treated Class 10.9 alloy steel and produced to ISO 7380 standards. The 8mm length provides improved clamping reliability in thicker or multi‑component assemblies, while the low‑profile button head maintains a smooth, finished appearance in clearance‑restricted or visible 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 minimize the risk of hydrogen embrittlement—ideal for mechanical, automotive, and industrial use.
