العربية DIN 6916 structural washers factory
XZ Fastener manufactures DIN 6916 structural washers for steel construction buyers who need hardened washers matched with high-strength bolting assemblies. These washers are commonly used with DIN 6914 structural bolts and DIN 6915 structural hex nuts in bridges, buildings, industrial frames, and heavy equipment connections. Factory supply should confirm washer size, hardness requirement, material, surface finish, hole diameter, outside diameter, thickness, packing, and inspection records before production. When EN 14399 or a project-specific assembly system is required, buyers should state that requirement before quotation.

Quick Specs
What Buyers Should Know Before Sourcing DIN 6916 Structural Washers
DIN 6916 structural washers are used to distribute load and protect connected steel surfaces in high-strength bolted joints. They are not ordinary flat washers. Thickness, hardness, hole diameter, outside diameter, and coating condition must match the structural bolting assembly.
In many project lists, DIN 6916 washers are ordered with DIN 6914 bolts and DIN 6915 nuts. Before factory production, compare the requirement with the DIN and ISO fastener standards guide. If the project requires EN 14399 assemblies, that requirement should be confirmed before manufacturing.
Common Purchasing Descriptions
Structural washer orders are often placed with bolts, nuts, and general metric fasteners. XZ Fastener can review DIN 6916 lines 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 | Factory Confirmation Point |
|---|---|
| DIN 6916 M20 structural washers plain | Confirm washer standard, nominal size, hardness, dimensions, and surface condition |
| DIN 6916 washers for DIN 6914 structural bolts | Confirm matching bolt size, nut requirement, finish, and set packing |
| Hot dip galvanized DIN 6916 structural washers | Confirm coating thickness, washer dimensions after coating, and assembly fit |
| DIN 6914 bolts with DIN 6915 nuts and DIN 6916 washers | Confirm complete set content, lot traceability, carton labels, pallet marks, and inspection package |
For related washer supply, review XZ Fastener flat washers.
Detailed Specifications Table
| Specification Item | Typical Requirement | Buyer Checkpoint |
|---|---|---|
| Standard | DIN 6916 | Confirm whether DIN 6916, EN 14399, or a project-specific equivalent is required |
| Assembly Match | Commonly used with DIN 6914 bolts and DIN 6915 nuts | Confirm washer-only supply or complete assembly supply before production |
| Dimensions | Nominal size, inside diameter, outside diameter, and thickness according to standard | Check against drawing, standard table, and project tolerance requirement |
| Hardness | Hardened washer performance according to structural bolting requirement | Confirm hardness test, sampling rule, and certificate format if required |
| Material | Carbon steel or alloy steel according to mechanical requirement | Confirm heat number, material certificate, and heat treatment route |
| Finish | Plain, oiled, black, hot dip galvanized, zinc flake, or project coating | Confirm coating compatibility with bolts, nuts, and installation requirement |
| Packing | Bulk cartons, set packing, wooden cases, or pallets | Confirm size, lot number, part number, quantity, gross weight, and pallet marks |
Material and Grade Explanation
DIN 6916 washers are selected for structural bolting systems, so material and hardness must support the load distribution expected in the joint. A general-purpose washer may look similar, but it may not provide the same bearing performance under structural preload.
For project supply, buyers should confirm whether hardness records, material traceability, heat treatment records, and third-party inspection are required. If the order includes bolts, nuts, and washers together, the set should be reviewed as one assembly.
Surface Finish Selection Guide
| Finish | Factory Use Consideration |
|---|---|
| Plain or Oiled | Controlled 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 consistent assembly surfaces |
For coating-sensitive assemblies, compare XZ Fastener coated fasteners before confirming the production route.
Manufacturing and Quality Control
Structural washer production requires dimensional consistency, correct hardness, coating control, and practical packing. Lot traceability should connect raw material, heat treatment, inspection, coating, and final shipment records.
- Review project drawings, DIN 6916 requirement, bolt standard, nut standard, and finish requirement.
- Confirm raw material, heat number, heat treatment, and hardness target.
- Control stamping or machining, inside diameter, outside diameter, thickness, and flatness during production.
- Inspect dimensions, hardness, surface condition, burrs, coating appearance, and marking or labeling requirement.
- Check compatibility with matching structural bolts and nuts when supplied as sets.
- Pack by size, lot, set content, carton quantity, pallet mark, and document package.
For complete structural assemblies, compatible industrial bolts and industrial nuts can be reviewed with the washer order.
Applications
DIN 6916 structural washers are used in high-strength steel bolting assemblies where load distribution and bearing surface control are important. Selection should follow the approved engineering drawing and installation requirement.
- 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
How to Get a Faster Quotation
A DIN 6916 factory quotation is faster when the washer requirement is provided together with the matching bolt and nut details. This reduces wrong-size supply, coating mismatch, and incomplete set packing.

|---|---|
| Size List | M20, M22, M24, M27 according to project list |
| Assembly Requirement | DIN 6916 washers with DIN 6914 bolts and DIN 6915 nuts |
| Mechanical Requirement | Hardness, material, heat treatment, or project-specific acceptance rule |
| Finish | Plain, black, hot dip galvanized, zinc flake, or project coating |
| Quantity | Pieces per size, assembly sets, batch shipment, or project total |
| Packaging and Inspection | Bulk carton, set packing, pallet marks, material certificate, dimensional report, hardness report |

FAQ
What are DIN 6916 structural washers used for?
DIN 6916 structural washers are used in high-strength steel bolting assemblies, commonly with DIN 6914 bolts and DIN 6915 nuts for buildings, bridges, industrial frames, and heavy structural projects.
Are DIN 6916 washers the same as general flat washers?
No. DIN 6916 washers are structural washers with dimensional and hardness requirements for high-strength bolting assemblies. General flat washers should not be substituted unless the project engineer approves the change.
Can DIN 6916 structural washers be hot dip galvanized?
Hot dip galvanized finish can be supplied when specified. Coating thickness, washer dimensions, and compatibility with the matching bolt and nut should be checked after coating.
Can XZ Fastener supply complete structural bolt assemblies?
Yes. DIN 6916 washers can be supplied with matching DIN 6914 bolts and DIN 6915 nuts when the size, finish, packing, and inspection requirements are confirmed.
What inspection records should buyers request?
Common records include material certificate, dimensional inspection report, hardness test, coating report when required, and packing list by lot.
What information is needed for a DIN 6916 quotation?
Send the size list, hardness or project requirement, finish, quantity, matching bolt and nut details, packaging method, inspection documents, and any project-specific standard or drawing.
