Bolts
U-Bolts & J-Bolts Supplier
As a supplier of u-bolts & j-bolts, 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.
Because U-bolts and J-bolts are formed to fit a specific pipe, tube, or anchoring situation rather than sold off a standard size chart the way a hex bolt is, the single most important number on the order isn't the thread size — it's the inside dimension across the bend, which has to match the outer diameter of whatever it's clamping. A U-bolt cut a few millimeters too tight or loose either won't fit or won't clamp securely.

Minimum Order — Container Quantity (Approx.)
A standard 20ft container (~20 tons) holds approximately 100,000-160,000 pieces of U-bolts/J-bolts sized for common pipe diameters. Exact quantity depends on the bend size and thread length 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.
