Bolts

High-Tensile Structural Bolts Exporter

We export high-tensile structural bolts worldwide, handling customs documentation, HS code classification, and FOB/CIF/CFR shipping terms end-to-end.

As an exporter, our job is the paperwork and logistics that make international trade actually work: HS code classification, commercial invoicing, certificates of origin, and container booking under your preferred Incoterm — so the product clears customs and arrives without delay.

Buyers evaluating us specifically in the exporter role are usually less concerned with manufacturing detail and more concerned with whether the shipment will clear customs smoothly and arrive on schedule — which is why documentation accuracy and Incoterm clarity matter as much here as the product specification itself.

High-strength friction-grip bolting works on a principle that surprises people outside structural engineering: the joint doesn't primarily rely on the bolt shank resisting shear at all. Instead, the bolt clamps the connected plates together so tightly that friction between the plates themselves transfers the load — which is why installation torque (or the direct-tension method used to verify it) matters as much as the bolt's material grade.

Minimum Order — Container Quantity (Approx.)

A standard 20ft container (~20 tons) holds approximately 60,000-100,000 sets of high-tensile structural bolt assemblies (bolt, nut, washers) in common sizes (M16-M20). 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.

Specifications

Standards

ASTM A325 (Type 1/3), ASTM A490, IS 3757, EN 14399.

Assembly

Supplied as matched sets — bolt, nut, and hardened washers — to ensure certified proof-load performance.

Size range

M12 to M36 metric; 1/2" to 1 1/2" imperial.

Finish

Plain, hot-dip galvanized, or mechanically galvanized (Type 3 weathering steel on request).

Applications

Structural steel fabrication

Beam, column, and truss connections in buildings and industrial structures.

Bridges & infrastructure

High-load structural connections requiring certified friction-grip assemblies.

Towers & transmission structures

Lattice tower and transmission structure bolting.

Materials Available

Steel

Medium-carbon alloy steel, quenched & tempered

Every assembly is proof-load and hardness tested to ASTM A325/A490 or IS 3757, with mill test certificates supplied for structural sign-off.

Our Process

  1. 1

    Spec confirmation

    Confirm standard, grade, size, and galvanizing requirement from structural drawings.

  2. 2

    Forging & heat treatment

    Hot forging followed by quench-and-temper heat treatment to reach the required tensile grade.

  3. 3

    Proof-load testing

    Batch proof-load and hardness testing with certification traceable to heat number.

  4. 4

    Export packing

    Matched bolt/nut/washer sets, boxed and documented for project-based export shipment.

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.
