Bolts
Hex Bolts Supplier
As a supplier of hex bolts, we hold ready stock across common sizes and grades for fast turnaround on repeat and project orders.
As a supplier, we act as your ongoing sourcing partner — whether that means matching an existing specification, filling a recurring order schedule, or sourcing a specific grade or finish you can't get reliably elsewhere.
This role suits buyers who've already settled on a specification and need a dependable source for it over time, rather than re-evaluating quality and pricing on every order — the relationship is built around consistency against an agreed baseline.
The hex head is popular precisely because it's a compromise that works everywhere: six flats give a wrench or socket enough surface area to apply high torque without rounding off, while the head stays compact enough to fit into most structural and mechanical layouts. That's why hex bolts, more than any other head style, end up specified as the default fastener across construction, machinery, and vehicle assembly.
Minimum Order — Container Quantity (Approx.)
A standard 20ft container (~20 tons) holds approximately 400,000-600,000 pieces of hex bolts in common sizes (M10-M12) — smaller diameters yield more pieces, larger structural sizes far fewer. Exact quantity depends on the specific size and grade ordered 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
Order & spec confirmation
Confirm standard, grade, size, quantity, and finish before production or sourcing begins.
- 2
Manufacturing / sourcing
Cold-forging, hot-forging, or machining depending on size and grade, with in-process dimensional checks.
- 3
Quality inspection
Batch sampling for tensile strength, hardness, thread gauge, and finish before packing.
- 4
Export packing & documentation
Corrosion-protected packing, container loading, and full export documentation (invoice, packing list, COO, MTC).
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.
