Designed for precision metric fastening where extended length and dependable strength are required, this M2.5‑0.45 x 16mm button socket cap screw is manufactured from high‑strength Class 10.9 alloy steel and produced to ISO 7380 standards. The 16mm length allows for deep thread engagement in thicker or multi‑layer assemblies, enhancing joint security and stability. Its low‑profile button head maintains a smooth, finished appearance in clearance‑restricted or visible installations, while the internal hex drive supports accurate torque application. Finished with a thermal black oxide coating, it provides reduced glare, mild corrosion resistance, and a uniform technical finish ideal for electronics, instrumentation, and precision mechanical assemblies.
