Anchors
Anchor Bolts Manufacturer
Global Fasteners Exports manufactures anchor bolts in-house and through certified partner mills, with batch testing and mill test certificates available on every order.
As a manufacturer, our role is to control quality from raw material through to finished, inspected product — cold-forging, hot-forging, or precision machining in-house or through certified partner mills, with batch testing against whichever standard your project specifies.
This is the role that matters most when a buyer needs traceability: a heat number on a mill test certificate, dimensional inspection records, and a documented process from raw bar stock to finished, packed product. Buyers evaluating us specifically as a manufacturer — rather than a trading intermediary — should ask to see this documentation rather than take quality claims at face value.
Anchor bolts are cast into concrete before it cures, which means there's no second chance to fix a placement error the way there is with a post-installed anchor — the embedment depth, projection length, and bolt pattern all need to be correct on the structural drawing before the pour, not adjusted afterward. This is why anchor bolt orders are almost always tied to an approved structural drawing rather than a generic catalog size.

Minimum Order — Container Quantity (Approx.)
A standard 20ft container (~20 tons) holds approximately 30,000-60,000 pieces of anchor bolts in common sizes (M12-M16), fewer for longer, larger-diameter foundation bolts. 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.
