Designed for metric fastening applications requiring added length and reliable strength, this M5‑0.80 x 12mm button socket cap screw is manufactured from high‑strength Class 10.9 alloy steel and produced to ISO 7380 standards. The 12mm length provides improved thread engagement for secure clamping in mechanical and machinery assemblies, while the low‑profile button head maintains a smooth, finished appearance in clearance‑restricted or visible installations. Featuring an internal hex drive for accurate torque application, it is finished with a thermal black oxide coating that reduces glare, offers mild corrosion resistance, and delivers a consistent technical finish suitable for industrial and precision mechanical use.
