M3‑0.50 x 10mm Button Socket Cap Screw – Class 10.9, Black Oxide, ISO 7380

Built for precision metric fastening where added length and strength are required, this M3‑0.50 x 10mm button socket cap screw is manufactured from Class 10.9 alloy steel and produced to ISO 7380 standards. The longer thread length improves clamping reliability in thicker or stacked components, while the smooth, low‑profile button head supports clean installation in space‑limited or visible assemblies. Finished with a thermal black oxide coating, it provides reduced glare, light corrosion resistance, and a uniform technical appearance well suited for electronics, instrumentation, and mechanical assemblies.
