M8 Hex Nuts Zinc Plated
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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as part of a fastener set for retail sale
Nuts sold in sets with screws or bolts may classify under 'screws, bolts, and nuts' headings based on principal use.
If non-threaded or rivet-style
Lacks threading, shifting to 'other non-threaded articles' in the same chapter.
If specifically designed as OEM parts for vehicle suspension
End-use as automotive body parts takes precedence over generic nut classification.

Import Tips & Compliance
• 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
