Hex Nuts Supplied from Turkey
FastenersFromTurkey directly supplies hex nuts—also called hexagon nuts—from Turkey for industrial export RFQs. DIN 934, ISO 4032 coarse, ISO 8673 fine, ASME B18.2.2 and buyer-specific requirements are fulfilled to the stated thread, class or grade, coating, documents and quantity.
- DIN 934 successor references checked by thread series and geometry
- Nut class or grade reviewed with the mating bolt or stud
- Material, coating, proof requirement and documents confirmed per RFQ

Fasteners From Turkey
Confirmed per RFQ
| Field | Order input | Confirmation |
|---|---|---|
| Product scope | Standard hex nut for the stated joint and mating fastener | Type and geometry confirmed per RFQ |
| Standard | ISO 4032 coarse, ISO 8673 fine, stated DIN 934 edition, ASME B18.2.2 or buyer specification | Exact standard and revision confirmed |
| Thread | Metric coarse or fine, or inch UNC or UNF, with tolerance requirement | Thread systems are never mixed |
| Class and mating part | Nut class or grade plus mating bolt or stud designation | Joint compatibility confirmed per RFQ |
| Material and coating | Material, finish, coating allowance and corrosion requirement | Order requirement confirmed before quotation |
| Proof and documents | Proof-load basis, tests, certificate, inspection and traceability scope | Deliverables confirmed per order |
| Commercial | Quantity, packing, Incoterm and destination | Commercial basis stated in the quotation |
| Supplier role | FastenersFromTurkey directly supplies hex nuts from Turkey. | Supply scope follows the RFQ |
DIN 934 to ISO 4032 for coarse thread or ISO 8673 for fine thread is not automatic interchange approval.
Configuration
Define the nut and mating fastener together
Thread designation, nut style, class or grade and coating allowance must suit the specified bolt or stud. Heavy hex nuts use a separate geometry and require their own RFQ.
Metric fine-thread hex nuts
State the ISO 8673 fine-thread designation, pitch, class, mating bolt or stud and coating allowance.
Request quoteInch-series hex nuts
State ASME B18.2.2 geometry, UNC or UNF thread, ASTM or SAE grade and the mating fastener separately from metric requirements.
Request quoteStandards and RFQ inputs
Hex nut specification boundaries
The nut must be qualified with the mating external thread and the governing joint specification.
| Decision | What to specify | Qualification rule |
|---|---|---|
| Metric coarse thread | ISO 4032 or exact stated DIN 934 edition | DIN 934 → ISO 4032 is a successor mapping for the applicable coarse-thread geometry, not automatic interchange |
| Metric fine thread | ISO 8673 or exact stated DIN 934 edition | Fine-thread designation and pitch must be explicit; do not infer ISO 4032 |
| Inch hex nut | ASME B18.2.2 with UNC or UNF thread | Do not convert an inch RFQ into a metric substitute |
| Mechanical requirement | ISO 898-2 nut class, ASTM grade, SAE J995 grade or buyer specification | Pairing must follow the governing joint specification; cross-system comparisons are not approvals |
| Coating and thread fit | Finish, coating thickness, lubrication and any over-tap requirement | Confirm final thread fit with the mating fastener and coating process |
| Proof and documents | Proof-load basis, test reports, certificate type, traceability and marking | EN 10204 3.1 and the specified proof, inspection, traceability and marking documents are supplied with the order |
Why FastenersFromTurkey
Direct supply qualified against the mating thread
FastenersFromTurkey directly supplies the requested hex nut requirement from Turkey across standard, thread, grade, coating, proof-load and documentation demands.
Standard and pitch review
Coarse, fine and inch threads are kept distinct, and legacy references are checked against the exact requested geometry.
Bolt-nut compatibility
Nut class or grade, proof requirement, coating and thread fit are reviewed with the mating bolt or stud.
Export quotation scope
Quantity, packing, destination, Incoterm, testing and document requirements are recorded in the quotation basis.
Quality and documents
Agree proof and inspection evidence
Proof-load, dimensional, coating and certificate requirements remain order-specific.
Mechanical evidence
State the governing nut class or grade, proof requirement and required mechanical reports.
Thread gauging
Define thread designation, tolerance, coating allowance and any required gauge or final-fit inspection.
Coating and traceability
Specify coating, test method, acceptance criterion, lot traceability and required certificate type.
Applications
The complete joint controls selection
Hex nuts can serve machinery, fabricated equipment, general industrial assembly and maintenance when the mating fastener is fully specified.
Machinery and equipment
Provide the bolt or stud designation, joint load, tightening method and service conditions.
Fabricated assemblies
State washer arrangement, bearing surface, coating, thread engagement and inspection requirements.
Replacement and maintenance
Supply the original standard, thread and grade; across-flats size or visual similarity is not enough.

RFQ FAQ
Hex nut buying questions
Is DIN 934 automatically interchangeable with ISO 4032?
No. ISO 4032 is the relevant coarse-thread successor reference in many cases, but exact geometry, size coverage, class, thread and joint approval must be checked.
When does ISO 8673 apply?
ISO 8673 covers fine-pitch metric hex nuts. The pitch must be stated explicitly; a DIN 934 label does not permit an automatic choice between ISO 4032 and ISO 8673.
Is a heavy hex nut the same as a standard hex nut?
No. A heavy hex nut has a different geometry and must be submitted as a separate RFQ with its governing standard, dimensions, grade, mating bolt or stud and proof-load requirement.
What should I send for a hex nut quote?
Send the standard, thread system and pitch, nut class or grade, mating bolt or stud, material, coating, proof and test requirements, certificates, quantity, packing, Incoterm and destination.
