Bolts
Carriage Bolts Wholesaler
We wholesale carriage bolts in bulk to distributors, retailers, and hardware stockists, with volume pricing and container-load (FCL/LCL) shipping options.
As a wholesaler, we hold ready stock across common sizes and grades and supply distributors, retailers, and hardware stockists at volume pricing — the buyer relationship here is about consistent supply and competitive per-unit cost at container-load quantities.
Wholesale buyers typically care more about consistent lead time and pricing stability across repeat orders than about a single one-off transaction, which is why we hold ready stock specifically for the sizes and grades that move fastest, rather than manufacturing every order from scratch.
The square neck under a carriage bolt's head is the whole point of the design: as the nut is tightened, the neck pulls itself into a matching square hole or embeds into timber, stopping the bolt from spinning even though there's nothing to hold a wrench against on top. That self-locking behavior is why carriage bolts remain the standard choice for one-person installation on decks, fences, and playground equipment, where a second wrench simply isn't practical.
Minimum Order — Container Quantity (Approx.)
A standard 20ft container (~20 tons) holds approximately 350,000-500,000 pieces of carriage bolts in common sizes (M8-M10). Exact quantity depends on size and length 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.

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.
