Nuts

Hex Nuts Manufacturer, Wholesaler, Supplier & Exporter

Hex nuts are paired with hex bolts and studs across nearly every industrial application. We manufacture and stock hex nuts and hex thin nuts across standard and high-tensile grades, ready for immediate export or bulk wholesale supply.

A nut is only as good as the bolt it's matched to, which is why buyers who source nuts and bolts from different suppliers occasionally run into assembly problems that have nothing to do with either part being defective on its own — a slightly different thread tolerance class or pitch standard between the two can produce a joint that turns by hand but never reaches proper clamping torque.

Thread pitch matters more than diameter alone. Coarse-pitch threads (the default for most structural and general-purpose work) assemble faster and resist cross-threading better; fine-pitch threads hold torque better under vibration and allow finer adjustment, which is why they show up more often in precision machinery and automotive applications. Buyers switching from coarse to fine pitch for the same nominal diameter need a genuinely different nut, not just a different note on the purchase order.

Assorted hex nuts and bolts

Minimum Order — Container Quantity (Approx.)

A standard 20ft container (~20 tons) holds approximately 1.2-1.6 million pieces of hex nuts in common sizes (M10-M12). 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.

How We Manufacture & Export This Product

  1. 1

    Spec matching

    Confirm thread pitch and grade against the mating bolt/stud before production.

  2. 2

    Forming

    Cold-forged or machined depending on size, with thread rolling for dimensional accuracy.

  3. 3

    Inspection

    Thread gauge, hardness, and proof-load testing on sample batches.

  4. 4

    Export packing

    Bulk carton or drum packing suited to container loading, with full export documentation.

Export Track Record

Regularly supplied as matched bolt-and-nut sets in container-load quantities for construction and OEM buyers.

Real-World Use Cases

General bolted assemblies

Paired with hex bolts and threaded rod across nearly every industrial and construction application.

Flange and pressure joints

High-tensile nuts matched to stud bolts in piping and pressure-vessel flange connections.

Machinery and equipment assembly

Standard fastening across frames, guards, and access panels.

Common Mistakes Buyers Make

Sourcing nuts and bolts from different specs

A nut and bolt that both look correct can still fail to reach proper clamp load if their thread tolerance classes don't match.

Using coarse-pitch nuts on fine-pitch bolts

They may thread partway on before binding — always confirm pitch, not just nominal diameter.

Under-specifying grade for the mating bolt

A lower-grade nut on a high-tensile bolt becomes the joint's weak point, regardless of the bolt's rating.

Glossary of Terms

Thread pitch
The distance between adjacent threads — coarse pitch is the general-purpose default; fine pitch improves vibration resistance and adjustment precision.
Thin nut
A reduced-height nut (DIN 936) used as a locknut or where axial space is limited.
Proof load rating
The tensile load a nut can withstand without thread stripping or permanent deformation, matched to the mating bolt's grade.

Quality Inspection We Perform

Dimensional inspection

Thread gauge, length, diameter, and head/drive geometry checked against the specified standard.

Material verification

Grade and material composition confirmed against the order specification, with mill test certificates on request.

Mechanical testing

Tensile strength, hardness, and proof-load testing on sample batches, particularly for structural and high-tensile grades.

Finish & coating check

Plating thickness, galvanizing coverage, or passivation quality inspected before packing.

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.

Packaging & Export Labeling

Export packing is chosen to survive ocean freight and container loading without corrosion or damage: corrosion-protected paper or oil coating where needed, then cartons, drums, or bulk bags, palletized or crated for the container. We can match specific labeling, barcoding, or carton-marking requirements for OEM and repeat buyers.

How to Choose a Reliable Hex Nuts Manufacturer, Wholesaler, Supplier & Exporter

Why matching a nut to its bolt matters more than most buyers assume, and how to evaluate a hex nut supplier on specification accuracy rather than price alone.
