M6‑1.00 Metric Hex Serrated Flange Nut, Class 8, Coarse Thread, Plain Finish

Manufactured from Class 8 steel, this M6‑1.00 hex serrated flange nut delivers strong, vibration‑resistant fastening in metric assemblies. The serrated flange bites into the mating surface to help prevent loosening and eliminates the need for a separate washer.
