M5‑0.80 Metric Hex Serrated Flange Nut, Class 8, Coarse Thread, DIN 6923, Zinc‑Yellow CR+6 Finish

Manufactured to DIN 6923 standards from Class 8 steel, this M5‑0.80 hex serrated flange nut provides strong, vibration‑resistant fastening in metric assemblies. Serrations on the integrated flange bite into the mating surface to help prevent loosening and eliminate the need for a washer. Finished with a zinc‑yellow CR+6 coating, it offers enhanced corrosion resistance and easy visual identification for automotive, industrial, and general‑purpose applications.
