M5‑0.80 x 25mm Button Socket Cap Screw – Class 10.9, Black Oxide, ISO 7380

Designed for metric fastening applications that require extended length and high load capacity, this M5‑0.80 x 25mm button socket cap screw is manufactured from heat‑treated Class 10.9 alloy steel and produced to ISO 7380 standards. The longer 25mm length allows for deep thread engagement through thicker components, enhancing joint strength and stability. Its low‑profile button head provides a smooth, finished appearance while reducing snagging in exposed or clearance‑limited assemblies. Featuring an internal hex drive for controlled 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, machinery, and precision mechanical use.
