العربية DIN 6914 structural bolts factory
XZ Fastener manufactures DIN 6914 structural bolts for steel construction buyers who need high-strength bolting assemblies with controlled dimensions, mechanical performance, and traceable production records. These bolts are commonly paired with DIN 6915 heavy hex nuts and DIN 6916 washers for structural steel joints, bridges, buildings, and industrial frames. Factory supply should start with the project specification: size, length, property class, coating, compatible nut and washer set, packaging, and inspection documents. Where EN 14399 or another project standard is required, confirm it before production.

Quick Specs
What Buyers Should Know Before Sourcing DIN 6914 Structural Bolts
DIN 6914 structural bolts are not standard hex bolts used for light assembly. They are part of a high-strength structural bolting system and are commonly ordered with DIN 6915 nuts and DIN 6916 washers. In real projects, the bolt alone is rarely the full requirement.
Many steel construction specifications now refer to EN 14399 assemblies or project-specific approval rules. Before production, compare the drawing and bill of materials with the DIN and ISO fastener standards guide, then confirm whether DIN 6914 is still the governing requirement or only a legacy reference.
Common Purchasing Descriptions
Structural bolt orders may appear beside general metric hex bolt items in one procurement file. XZ Fastener can review DIN 6914 descriptions together with related lines 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 | Factory 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, coating compatibility, packing sets, and inspection records |
| Hot dip galvanized DIN 6914 structural bolt assemblies | Confirm coating thickness, oversize nut fit, thread engagement, and project acceptance rule |
| DIN 6914 structural bolts for steel frame project | Confirm project standard, lot traceability, documents, carton labels, and pallet marks |
For related project hardware, review XZ Fastener high-strength fasteners.
Detailed Specifications Table
| Specification Item | Typical Requirement | Buyer Checkpoint |
|---|---|---|
| Estándar | DIN 6914 | Confirm whether DIN 6914, EN 14399, or a project-specific equivalent is required |
| Assembly | Bolts commonly paired with DIN 6915 nuts and DIN 6916 washers | Confirm whether the order is bolt-only or a complete bolting set |
| Fuerza | High-strength structural bolting, commonly Class 10.9 where specified | Confirm mechanical test requirements, head marking, and certificate format |
| Material | Carbon steel or alloy steel according to mechanical property requirement | Confirm heat treatment route 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 assembly torque behavior |
| Inspection | Dimensional checks, hardness, tensile, proof load, thread fit, coating inspection | Confirm test frequency, sampling rule, and third-party inspection if required |
| 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 typically selected for high-strength steel connections. The factory must control raw material, heat treatment, hardness, tensile strength, and head marking because these bolts are used in load-bearing assemblies.
For critical structures, the bolt grade cannot be selected in isolation. Matching nuts and washers must meet the same project system. Buyers should review the complete bolting assembly, especially when preload, slip resistance, or site tightening records are required.
Surface Finish Selection Guide
| Finish | Structural 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
A structural bolt factory order should be controlled as a project component, not a simple commodity. Each lot needs clear traceability from raw material to heat treatment, threading, inspection, coating, and final packing.
- 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.
- Pack by size, lot, assembly set, carton quantity, pallet mark, and document package.
When buyers need non-standard lengths, special marking, or project-specific packing, XZ Fastener can discuss custom fasteners according to order requirement.
Aplicaciones
DIN 6914 structural bolts are used where steel members must be connected with high-strength bolting assemblies. They should be selected by the project engineer or according to the approved steel structure specification.
- Steel buildings and warehouse frame connections
- Bridge steelwork and heavy 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.
How to Get a Faster Quotation
Structural bolt quotations move faster when the request includes the full assembly requirement. If the project needs bolts, nuts, washers, coating, and inspection records, list them together instead of sending separate descriptions.
| Information Needed | Example |
|---|---|
| Size List | M20 x 80, M22 x 90, M24 x 100 according to project list |
| Assembly Requirement | DIN 6914 bolts with DIN 6915 nuts and DIN 6916 washers |
| Strength and Material | High-strength structural bolting, Class 10.9 where specified |
| Finish | Plain, black, hot dip galvanized, zinc flake, or project coating |
| Cantidad | Pieces per size, assembly sets, batch shipment, or project total |
| Packaging and Inspection | Set packing, pallet marks, material certificate, dimensional report, mechanical test report |

Preguntas frecuentes
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.
Are DIN 6914 bolts supplied with nuts and washers?
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.
Is DIN 6914 the same as EN 14399?
No. Some projects may reference older DIN standards, while others require EN 14399 assemblies. Buyers should confirm the governing standard in the drawing or project specification before ordering.
What inspection records should buyers request?
Common records include material certificate, dimensional inspection report, hardness test, tensile or proof load test, thread fit check, coating report when required, and packing list by lot.
What information is needed for a DIN 6914 quotation?
Send the size list, strength requirement, finish, quantity, nut and washer requirement, packaging method, inspection documents, and any project-specific standard or drawing.
