Hex Bolts Manufacturer, Wholesaler, Supplier & Exporter
Hex Bolts manufacturer, wholesaler, supplier and exporter from India. Global Fasteners Exports is a trading and export company: our hex bolts are made to DIN 931, DIN 933, ISO 4014, ISO 4017 standards by partner factories and supplied to importers, distributors and OEMs in 222+ countries from 10,000 pcs, or a half or full container, at competitive prices below the average wholesale price.
Hex bolts are the most widely specified fastener in construction, machinery, and structural assembly. Our partner factories manufacture hex bolts to DIN, ISO, and ASTM dimensional standards across a full range of materials and grades, and we ship them as full container loads (FCL) or palletized LCL shipments to buyers worldwide.
The hex head is popular precisely because it's a compromise that works everywhere: six flats give a wrench or socket enough surface area to apply high torque without rounding off, while the head stays compact enough to fit into most structural and mechanical layouts. That's why hex bolts, more than any other head style, end up specified as the default fastener across construction, machinery, and vehicle assembly.
Buyers new to sourcing hex bolts often assume 'hex bolt' is a single specification, but the standard, grade, and thread pitch all move independently of each other. A DIN 933 M12 bolt in property class 8.8 is a different part from an ISO 4014 M12 in class 10.9, even though both look identical to the eye — the difference only shows up under load or in a mill test certificate. Getting this wrong doesn't usually fail immediately; it fails later, under stress, which is why buyers who skip specification detail on a first order often come back after a field failure asking for exact traceability on the next one.
Full-thread (DIN 933 / ISO 4017) versus partial-thread (DIN 931 / ISO 4014) is the other decision point that's easy to overlook. Full-thread bolts are more forgiving on unknown grip lengths and are typically cheaper to stock in volume; partial-thread bolts perform better in shear applications because the unthreaded shank carries load more evenly across the joint. Specifying the wrong one won't be visible in a parts bin, but it changes how the joint actually behaves.
Minimum order and container quantity
Minimum order
10,000 pcs
or half / full container, as per your requirement
Half container (20ft)
200,000-300,000 pcs
Full container (20ft)
400,000-600,000 pcs
A standard 20ft container (~20 tons) holds approximately 400,000-600,000 pieces of hex bolts in common sizes (M10-M12) — smaller diameters yield more pieces, larger structural sizes far fewer. Exact quantity depends on the specific size and grade ordered and is confirmed at quote time.
The minimum order is 10,000 pcs, so you don't need a full container to order: half-container and smaller LCL orders are available as well. 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 Supply & Export This Product
- 1
Order & spec confirmation
Confirm standard, grade, size, quantity, and finish before production or sourcing begins.
- 2
Manufacturing / sourcing
Cold-forging, hot-forging, or machining depending on size and grade, with in-process dimensional checks.
- 3
Quality inspection
Batch sampling for tensile strength, hardness, thread gauge, and finish before packing.
- 4
Export packing & documentation
Corrosion-protected packing, container loading, and full export documentation (invoice, packing list, COO, MTC).
Export Track Record
Shipped as full container loads (FCL) and LCL pallets to distributors and OEM buyers across multiple continents.
Real-World Use Cases
Structural steel connections
Beam-to-column and gusset-plate connections where a specific property class is called out on the fabrication drawing.
Machine base and frame assembly
General-purpose fastening for equipment frames, guards, and access panels.
Flange and bracket mounting
Piping supports and equipment brackets, often paired with matching high-tensile nuts and washers.
Vehicle and trailer chassis
Chassis and suspension mounting points specified to a defined property class for fatigue resistance.
Common Mistakes Buyers Make
Mixing property classes in one joint
Pairing an 8.8 bolt with a 10.9 nut (or vice versa) undermines the joint's rated proof load even though it assembles fine.
Ignoring full vs. partial thread
Substituting a full-thread bolt where a partial-thread bolt was specified changes shear performance in the grip zone.
Assuming DIN and ASTM grades are interchangeable
A DIN 8.8 bolt and an ASTM Grade 5 bolt have similar but not identical strength profiles — don't substitute without checking the actual mechanical property tables.
Skipping the finish spec on outdoor structures
A plain-finish bolt specified for an outdoor structure will corrode well before the structure's design life, even if the strength grade was correct.
Glossary of Terms
- Property class
- A two-part number (e.g. 8.8) stamped on the bolt head: the first number is roughly 1/100th of minimum tensile strength in MPa, the second is the yield-to-tensile ratio.
- Proof load
- The maximum load a bolt can withstand without permanent deformation — the practical basis for a joint's safe working load.
- Grip length
- The combined thickness of the parts being clamped together, used to select the correct bolt length.
- Full thread vs. partial thread
- Full-thread bolts are threaded along their entire shank; partial-thread bolts leave a smooth shank section for better shear performance.
- Torque-tension relationship
- The (imperfect) relationship between the torque applied to tighten a bolt and the actual clamping force achieved — affected by friction, lubrication, and finish.
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.
