العربية DIN 6914 structural bolts exporter
XZ Fastener exports DIN 6914 structural bolts for steel construction buyers who need high-strength bolting assemblies with controlled dimensions, reliable packing, and clear shipment documents. These bolts are commonly used with DIN 6915 heavy hex nuts and DIN 6916 washers for bridges, buildings, industrial frames, and heavy equipment connections. Export orders should confirm the governing standard, size list, property class, coating, nut and washer requirement, packing marks, and inspection records before production. If EN 14399 or project-specific approval is required, it should be stated clearly at the quotation stage.

Quick Specs
What Buyers Should Know Before Sourcing DIN 6914 Structural Bolts
DIN 6914 structural bolts are used in high-strength steel connections. They should be treated as part of a bolting system, not as loose general-purpose hex bolts. In many export projects, the buyer also needs compatible DIN 6915 nuts and DIN 6916 washers, with matching finish and inspection records.
Some projects still reference DIN 6914, while others require EN 14399 assemblies or a project-approved equivalent. Before placing the order, check the drawings and specification against the DIN and ISO fastener standards guide. This avoids document mismatch when the shipment reaches the project site.
Common Purchasing Descriptions
Export procurement files often contain both structural bolts and standard metric bolts. XZ Fastener can review DIN 6914 items together with related descriptions such as DIN 933 full thread hex bolts, Grade 8.8 carbon steel hex bolts, metric hex head bolts, zinc plated DIN 933 bolts, black oxide DIN 933 bolts, and hot dip galvanized DIN 933 bolts.
| Purchasing Description | Export Confirmation Point |
|---|---|
| DIN 6914 M20 x 80 structural bolts Class 10.9 plain | Confirm structural bolt standard, head dimensions, property class, marking, and test report |
| DIN 6914 bolts with DIN 6915 nuts and DIN 6916 washers | Confirm complete assembly, matching finish, packing sets, and lot traceability |
| Hot dip galvanized DIN 6914 structural bolt assemblies | Confirm coating thickness, nut clearance, thread engagement, and project approval rule |
| DIN 6914 structural bolts for export steel frame project | Confirm destination documents, pallet marks, net weight, gross weight, and inspection records |
For related heavy-duty supply, review XZ Fastener high-strength fasteners and wider fastener products.
Detailed Specifications Table
| Specification Item | Typical Requirement | Buyer Checkpoint |
|---|---|---|
| Standard | DIN 6914 | Confirm whether DIN 6914, EN 14399, or a project-specific equivalent is required |
| Assembly | Commonly paired with DIN 6915 nuts and DIN 6916 washers | Confirm bolt-only supply or complete bolting set before quotation |
| Strength | High-strength structural bolting, commonly Class 10.9 where specified | Confirm mechanical testing, head marking, and certificate format |
| Material | Carbon steel or alloy steel according to mechanical property requirement | Confirm heat treatment route, heat number, and material certificate requirement |
| Finish | Plain, oiled, black, hot dip galvanized, zinc flake, or project coating | Confirm coating effect on thread fit, nut clearance, and tightening behavior |
| Inspection | Dimensional checks, hardness, tensile, proof load, thread fit, coating inspection | Confirm sampling rule, test frequency, and third-party inspection if required |
| Export Packing | Bulk cartons, wooden cases, pallets, or assembly set packing | Confirm lot number, part number, size, quantity, gross weight, and pallet marks |
Material and Grade Explanation
DIN 6914 structural bolts are specified for high-strength steel joints. Material selection, heat treatment, hardness, tensile performance, and head marking should follow the project requirement. A similar-looking metric bolt is not acceptable if the approved drawing calls for a structural bolting system.
The complete assembly matters. Nuts and washers must match the required standard, coating, and mechanical performance. For critical projects, buyers should confirm whether preload, slip resistance, or installation records are part of the acceptance requirement.
Surface Finish Selection Guide
| Finish | Export Use Consideration |
|---|---|
| Plain or Oiled | Controlled indoor storage or projects requiring final site treatment |
| Black Finish | General protection for controlled environments, subject to project approval |
| Hot Dip Galvanized | Outdoor steelwork where thicker corrosion protection is required |
| Zinc Flake | Corrosion protection with controlled coating build and thread-fit management |
For coating-sensitive assemblies, compare XZ Fastener coated fasteners before confirming production.
Manufacturing and Quality Control
DIN 6914 export orders should be controlled from raw material to final packing. A clear production plan helps reduce site rejection, customs delay, and relabeling work at the destination warehouse.
- Review project drawings, DIN 6914 requirement, mating nut and washer standards, and finish requirement.
- Confirm raw material, heat number, heat treatment, and mechanical property targets.
- Control forming, thread rolling, head dimensions, shank length, and thread length during production.
- Inspect dimensions, head marking, hardness, tensile performance, proof load, and thread fit.
- Check coating appearance, coating thickness, and nut assembly after surface treatment.
- Prepare export packing, carton labels, pallet marks, invoice details, packing list data, and document package.
For special lengths, non-standard markings, or project-specific packing, XZ Fastener can discuss custom fasteners according to order requirement.
Applications
DIN 6914 structural bolts are used where steel members require high-strength bolting assemblies. Selection should follow the approved engineering specification and installation method.
- Steel buildings and warehouse frame connections
- Bridge steelwork and infrastructure joints
- Industrial platforms, towers, and equipment supports
- Power plant, mining, and petrochemical steel structures
- Heavy machinery frames where structural bolting is specified
Complete assemblies may require compatible industrial nuts and flat washers to match the project specification.

FAQ
What are DIN 6914 structural bolts used for?
DIN 6914 structural bolts are used for high-strength steel connections in buildings, bridges, industrial frames, platforms, and heavy structural projects where the specification requires this bolting system.
Can DIN 6914 structural bolts be exported with nuts and washers?
Yes. They can be supplied as bolt-only items or as assemblies with DIN 6915 nuts and DIN 6916 washers. Buyers should confirm whether the project requires complete sets.
Can DIN 6914 structural bolts be hot dip galvanized?
Hot dip galvanized finish can be supplied when specified. The matching nut clearance, coating thickness, thread fit, and assembly acceptance should be confirmed before production.
