M3‑0.50 x 25mm Button Socket Cap Screw – Class 12.9, Zinc Plated (Cr+3), ISO 7380

Built for high‑strength metric fastening where extended reach is required, this M3‑0.50 x 25mm button socket cap screw is manufactured from heat‑treated Class 12.9 alloy steel and produced to ISO 7380 standards. The longer shank supports secure fastening through thicker components, while the smooth, low‑profile button head allows for use in tight‑clearance or appearance‑sensitive assemblies. Finished with a mechanical zinc coating and trivalent chromium (Cr+3) passivation, it provides added corrosion resistance and a durable, uniform finish ideal for mechanical, automotive, and industrial applications.
