Socket Head Cap Screws Wholesaler
We wholesale socket head cap screws 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.
Socket head cap screws earn their place in precision machinery for a specific reason: the cylindrical head lets a designer sink the fastener flush or below the surface without sacrificing the wrench engagement needed for a high-tensile joint. That combination — compact head profile plus class-12.9 strength — is hard to get from any other head style, which is why mold bases, jigs, and fixtures default to socket screws almost everywhere.
Minimum Order — Container Quantity (Approx.)
A standard 20ft container (~20 tons) holds approximately 700,000-900,000 pieces of socket head cap screws in common sizes (M8-M10). 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.

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.
