Nuts
Hex Nuts Exporter
We export hex nuts worldwide, handling customs documentation, HS code classification, and FOB/CIF/CFR shipping terms end-to-end.
As an exporter, our job is the paperwork and logistics that make international trade actually work: HS code classification, commercial invoicing, certificates of origin, and container booking under your preferred Incoterm — so the product clears customs and arrives without delay.
Buyers evaluating us specifically in the exporter role are usually less concerned with manufacturing detail and more concerned with whether the shipment will clear customs smoothly and arrive on schedule — which is why documentation accuracy and Incoterm clarity matter as much here as the product specification itself.
A nut is only as good as the bolt it's matched to, which is why buyers who source nuts and bolts from different suppliers occasionally run into assembly problems that have nothing to do with either part being defective on its own — a slightly different thread tolerance class or pitch standard between the two can produce a joint that turns by hand but never reaches proper clamping torque.
Minimum Order — Container Quantity (Approx.)
A standard 20ft container (~20 tons) holds approximately 1.2-1.6 million pieces of hex nuts in common sizes (M10-M12). Exact quantity depends on size and grade and is confirmed at quote time.
You don't need a full container to order. Hurain Engitech & Trade — the group Global Fasteners Exports operates under — regularly ships smaller, partial-container (LCL) orders of just a few pallets or boxes for buyers who don't yet need FCL volume, consolidated with other cargo to keep freight cost reasonable.

Our Process
- 1
Spec matching
Confirm thread pitch and grade against the mating bolt/stud before production.
- 2
Forming
Cold-forged or machined depending on size, with thread rolling for dimensional accuracy.
- 3
Inspection
Thread gauge, hardness, and proof-load testing on sample batches.
- 4
Export packing
Bulk carton or drum packing suited to container loading, with full export documentation.
HS Code & Customs Classification
Most fasteners fall under HS Chapter 73 (articles of iron or steel) or Chapter 74/76 for brass and aluminum items — the exact 8-10 digit subheading depends on the specific product and material. We include the HS code on the commercial invoice; confirm the applicable import duty with your customs broker, since rates vary by country and trade agreement.
