M2.5‑0.45 x 8mm Button Socket Cap Screw – Class 10.9, Black Oxide, ISO 7380

Designed for precision metric fastening where added length and consistent strength are required, this M2.5‑0.45 x 8mm button socket cap screw is manufactured from high‑strength Class 10.9 alloy steel and produced to ISO 7380 standards. The 8mm length provides increased thread engagement for secure fastening in thicker or multi‑component assemblies, while the low‑profile button head maintains a smooth, finished appearance in tight or visible installations. Featuring an internal hex drive for accurate torque control, it is finished with a thermal black oxide coating that reduces glare, offers mild corrosion resistance, and delivers a uniform technical finish ideal for electronics, instrumentation, and light mechanical applications.
