Designed for precision fastening in compact metric assemblies, this M2‑0.40 x 6mm button socket cap screw is manufactured from high‑strength Class 10.9 alloy steel and meets ISO 7380 specifications. The increased length provides improved thread engagement for secure fastening in thin or multi‑layer components, while the low‑profile button head allows for a clean, space‑efficient installation. Finished with a thermal black oxide coating, it offers reduced glare, mild corrosion resistance, and a consistent technical appearance ideal for electronics, instrumentation, and light mechanical applications.
