M3‑0.50 x 5mm Button Socket Cap Screw – Class 10.9, Zinc‑Baked (Cr+3), ISO 7380

Manufactured for high‑strength precision fastening, this M3‑0.50 x 5mm button socket cap screw is produced from heat‑treated Class 10.9 alloy steel and conforms to ISO 7380 standards. The short 5mm length is ideal for compact, low‑clearance assemblies, while the low‑profile button head delivers a smooth, finished appearance. An internal hex drive allows accurate torque application, and the zinc‑baked finish with trivalent chromium (Cr+3) passivation provides improved corrosion resistance while minimizing the risk of hydrogen embrittlement—making it well suited for mechanical, automotive, and industrial applications.
