Fasteners From Turkey
Confirmed per RFQ
| Field | Order input | Confirmation |
|---|---|---|
| Product scope | Standard hex bolt with full or partial thread | Configuration confirmed per RFQ |
| Standard | ISO 4014, ISO 4017, stated DIN reference, ASME B18.2.1 or buyer specification | Exact standard and revision confirmed |
| Thread and dimensions | Metric or inch system, diameter, pitch, length, grip and tolerances | Thread systems are never mixed |
| Material and class | Required material and ISO 898-1 class, ASTM A307 grade, SAE J429 grade or buyer designation | No cross-system equivalence assumed |
| Finish or coating | Finish, coating system and stated corrosion requirement | Order requirement confirmed before quotation |
| Testing and documents | Mechanical, dimensional, coating and certificate requirements | Deliverables confirmed per order |
| Commercial | Quantity, packing, Incoterm and destination | Commercial basis stated in the quotation |
| Supplier role | FastenersFromTurkey directly supplies hex bolts from Turkey. | Supply scope follows the RFQ |
DIN 931 to ISO 4014 and DIN 933 to ISO 4017 are geometric successor references, not blanket approval to substitute.
Configuration
Define the hex bolt before pricing
A standard number alone does not settle thread length, mechanical designation, finish or document scope.
Fully threaded hex bolts
Confirm the full-thread standard, diameter, pitch, length, property requirement, coating and intended mating nut.
Request quoteInch-series hex bolts
State the ASME geometry, UNC or UNF thread, SAE or ASTM grade, dimensions and finish separately from metric requirements.
Request quoteStandards and RFQ inputs
Hex bolt specification boundaries
Use the governing purchase specification. Similar dimensions or familiar DIN and ISO labels do not establish automatic interchange.
| Decision | What to specify | Qualification rule |
|---|---|---|
| Partial metric thread | ISO 4014 or the exact stated DIN 931 edition | DIN 931 → ISO 4014 is a geometric successor mapping; verify dimensions and omitted sizes |
| Full metric thread | ISO 4017 or the exact stated DIN 933 edition | DIN 933 → ISO 4017 is a geometric successor mapping; verify dimensions and omitted sizes |
| Inch hex bolt | ASME B18.2.1 with UNC or UNF thread | Do not convert an inch RFQ into a metric substitute |
| Mechanical requirement | ISO 898-1 class, ASTM A307 grade, SAE J429 grade or buyer specification | ASTM A307 and SAE J429 are RFQ examples, not automatic equivalents to ISO classes |
| Finish and testing | Coating, thickness, corrosion target, lubrication and required tests | Coating performance is supplied to the stated test method and acceptance criteria |
| Documents | Certificate type, inspection report, traceability and marking | EN 10204 3.1 and the specified inspection, traceability and marking documents are supplied with the order |
Why FastenersFromTurkey
Direct supply based on the complete specification
FastenersFromTurkey directly supplies the requested hex bolt requirement from Turkey across standard, dimensional, grade, coating and documentation demands.
Standards boundary review
Legacy DIN and current ISO references are checked as geometry standards rather than treated as automatic substitution approval.
Mating-part check
Thread system, pitch, tolerance, bolt class and the specified nut or tapped part are reviewed together.
Export quotation scope
Quantity, packing, destination, Incoterm, testing and document requirements are recorded in the quotation basis.
Quality and documents
Agree evidence before quotation
Testing, inspection and certificate scope remain order-specific.
Mechanical evidence
State the governing class or grade and required mechanical reports; do not infer one system from another.
Dimensional and thread checks
Define the standard, revision, tolerance class and any inspection or gauge requirement.
Coating and traceability
Specify coating, test method, acceptance criterion, lot traceability and required certificate type.
Applications
The joint controls final selection
Hex bolts can serve machinery, fabricated equipment, general industrial assembly and maintenance when the joint specification is complete.
Machinery and equipment
Provide joint stack, grip, tightening method, service load and environmental conditions.
Fabricated assemblies
State hole condition, mating nut, washer arrangement, finish and inspection requirements.
Replacement and maintenance
Supply the original standard, dimensions and grade; visual similarity is not enough for substitution.

RFQ FAQ
Hex bolt buying questions
Are DIN 931 and ISO 4014 hex bolts automatically interchangeable?
No. DIN 931 to ISO 4014 is a geometric successor mapping, not blanket approval. Confirm the exact edition, diameter, pitch, dimensions, thread length, class, finish and joint approval before substitution.
Are DIN 933 and ISO 4017 the same in every size?
No. DIN 933 to ISO 4017 is also a geometric successor mapping. Dimensional differences and omitted diameters must be checked against the purchase specification.
Can metric and inch hex bolt requirements be combined?
No. Metric ISO threads and inch UNC or UNF threads are separate systems. State the governing geometry, thread designation and mechanical grade in the requested system.
What should I send for a hex bolt quote?
Send the standard or drawing, thread system, diameter, pitch, length, full or partial thread, class or grade, material, coating, tests, certificates, quantity, packing, Incoterm and destination.
