Screws
Set Screws / Grub Screws Supplier
As a supplier of set screws / grub 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.
Set screws (grub screws) do their job entirely below the surface of the component they're threaded into, which means the point geometry — not the thread — is what actually determines how well they hold a shaft in place. Buyers who order 'set screws' without specifying point type are leaving the single most important performance decision to whoever fills the order.
Minimum Order — Container Quantity (Approx.)
A standard 20ft container (~20 tons) typically holds 3-5 million pieces of set screws in common sizes (M6-M8). Exact quantity depends on size and point type 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.
