M2‑0.40 x 8mm Button Socket Cap Screw – Class 10.9, Zinc‑Baked (Cr+3), ISO 7380

Designed for precision metric fastening with added length, this M2‑0.40 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 thread engagement for secure fastening in small or multi‑component assemblies, while the low‑profile button head delivers a clean, finished appearance in tight or visible applications. Featuring an internal hex drive for accurate 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—ideal for mechanical, electronic, and industrial use.
