Quick Specs
What Buyers Should Know Before Sourcing DIN 6916 Structural Washers
DIN 6916 structural washers are not general flat washers. They are hardened washers used in high-strength bolted joints to support load distribution and protect bearing surfaces. For wholesale supply, dimensional consistency and hardness control matter as much as the visible finish.
DIN 6916 washers are often ordered with DIN 6914 bolts and DIN 6915 nuts. Before release, compare the project requirement with the DIN and ISO fastener standards guide. If the project requires EN 14399 or another approved assembly system, state it clearly before production.
Common Purchasing Descriptions
Structural washer orders are often supplied 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 | Wholesale Supply Checkpoint |
|---|---|
| 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 compatibility |
| DIN 6914 bolts with DIN 6915 nuts and DIN 6916 washers | Confirm set content, lot traceability, carton labels, pallet marks, and inspection package |
For related washer supply, review XZ Fastener flat washers.
Detailed Specifications Table

| Assembly Match | Commonly used with DIN 6914 bolts and DIN 6915 nuts | Confirm washer-only supply or complete assembly supply before quotation |
| Dimensions | Nominal size, inside diameter, outside diameter, and thickness according to standard | Check against drawing, standard table, and project tolerance requirement |
| صلابة | Hardened washer performance according to structural bolting requirement | Confirm hardness test, sampling rule, and certificate format if required |
| مادة | 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 |
| Wholesale 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 wholesale supply, buyers should confirm whether hardness records, material traceability, heat treatment records, and third-party inspection are required. If bolts, nuts, and washers are supplied together, the set should be reviewed as one assembly.
Surface Finish Selection Guide
| Finish | Wholesale 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 supply plan.
Manufacturing and Quality Control
Wholesale structural washer supply requires dimensional consistency, correct hardness, coating control, and practical packing. Lot traceability should connect raw material, heat treatment, inspection, coating, and 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 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.
