M3‑0.50 x 12mm Button Socket Cap Screw – Class 10.9, Black Oxide, ISO 7380

Intended for metric fastening applications requiring both strength and extended reach, this M3‑0.50 x 12mm button socket cap screw is manufactured from Class 10.9 alloy steel and conforms to ISO 7380 specifications. The increased length supports deeper thread engagement in thicker assemblies, while the rounded, low‑profile button head allows for smooth installation in clearance‑restricted or visible locations. Finished with a thermal black oxide coating, it delivers reduced glare, mild corrosion resistance, and a consistent technical appearance ideal for electronics, instrumentation, and precision mechanical assemblies.
