Rigging & Inserts
Turnbuckles & Threaded Inserts Supplier
As a supplier of turnbuckles & threaded inserts, 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.
A turnbuckle's entire function is mechanical advantage over tension: turning the center barrel draws two oppositely-threaded end fittings together, tightening whatever cable or rod is attached at each end. Getting the two ends threaded in opposite directions is what makes this work — which is also why a turnbuckle can't be repaired by threading a standard rod into one side.
Minimum Order — Container Quantity (Approx.)
A standard 20ft container (~20 tons) holds approximately 130,000-200,000 pieces of turnbuckles in common sizes (M8-M10). Exact quantity depends on size and end-fitting 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.
