M8 Hex Nuts Zinc Plated from Mexico
These are standard M8 hex nuts made from carbon steel with a zinc plating for corrosion resistance, used to secure bolts in machinery and construction. They fall under HTS 7318.16.0085 as 'other' threaded nuts of iron or steel, not specifically classified as machine screw nuts or locknuts. The hexagonal shape and metric threading distinguish them from square or specialty nuts.

Import Tips
• Verify plating type and thickness meets ASTM standards; declare exact material composition (e.g
• carbon steel grade) to avoid reclassification
• Provide mill test certificates for steel quality; common pitfall is undervaluation based on bulk packaging without weight verification
• Ensure nuts are not part of assemblies; import as loose articles to stay under this code
