Socket Head Cap Screws Supplier
As a supplier of socket head cap screws, 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.
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.
