Screws
Self-Tapping Screws Supplier
As a supplier of self-tapping 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.
The distinction between self-tapping and self-drilling trips up more first-time buyers than almost any other spec in this catalog. Self-tapping screws form threads into a pre-existing hole and rely on the installer (or a pre-drilling step) to get that hole right; self-drilling screws carry their own drill-point tip and skip the pre-drilling step entirely, at the cost of a slightly more expensive part. Ordering the wrong one for the job either wastes the drill-point cost or leaves installers drilling holes that should have been unnecessary.
Minimum Order — Container Quantity (Approx.)
A standard 20ft container (~20 tons) typically holds several million pieces of self-tapping screws in common sizes. Exact quantity depends on length, diameter, and head style, 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.
