M3‑0.50 x 8mm Button Socket Cap Screw – Class 10.9, Black Oxide, ISO 7380

This M3‑0.50 x 8mm button socket cap screw is engineered from high‑strength Class 10.9 alloy steel and manufactured to ISO 7380 standards for consistent quality and performance. The increased length allows for enhanced thread engagement in multi‑component or thicker assemblies, while the rounded, low‑profile button head provides a neat, finished appearance in space‑constrained or visible installations. Finished with a thermal black oxide coating, it offers reduced light reflection, mild corrosion resistance, and a uniform technical look ideal for electronics, instrumentation, and precision mechanical applications.
