M2.5‑0.45 x 12mm Button Socket Cap Screw – Class 10.9, Black Oxide, ISO 7380

Designed for precision metric fastening applications requiring extended length, this M2.5‑0.45 x 12mm button socket cap screw is manufactured from high‑strength Class 10.9 alloy steel and produced to ISO 7380 standards. The 12mm length provides deeper thread engagement for secure fastening in thicker or multi‑layer assemblies, while the smooth, low‑profile button head maintains a clean, finished appearance in clearance‑restricted or visible installations. Finished with a thermal black oxide coating, it offers reduced glare, mild corrosion resistance, and a uniform technical finish ideal for electronics, instrumentation, and precision mechanical assemblies.
