DIN 6916 Plain Chamfered Washers
DIN 6916 plain chamfered washers for high-strength structural bolting, system HV — thread sizes M12 to M36, the chamfered hardened washer of the German HV set (the DIN-era counterpart to EN 14399-6), with the collected geometry ladder and the kg/1000 pcs figures.

Specifications
DIN 6916 is the German-system HV structural washer — same job as EN 14399-6 (chamfered bearing face under the head or nut of a preloaded friction-grip set) and, on the collected ladder, the same M12 → M36 size run with nearly identical geometry: the M20 washer bores 21–21.33 mm on a 37 mm outside diameter at 4 mm nominal thickness in both standards. The practical differences are the ordering conventions and the ladder details — DIN 6916 prints an approximate chamfer value (single ≈ row rather than the EN table's min/max), and the source carries a kg/1000 pcs column (7.03 kg at M12 up to 115 kg at M36) that matters when the order is crates of washers for a steel yard. Where the assembly is specified in the European EN 14399 set, use the EN 14399-6 page in this catalog; where drawings name DIN 6916, order from this ladder by thread size. Property class, hardness and finish are not tabulated by the collected specification — per RFQ.

Materials
- Material and hardness specified per RFQ — hardened steel matched to the HV bolt set; state the assembly and any galvanizing on the RFQ and the pairing is confirmed at quotation
Ordering & documentation
Documents
Shipments are backed by Mill Test Certificate (MTC), Dimensional Report, Salt Spray Test Report on request, with full batch traceability from raw material to finished product. Quality management follows the owner-confirmed compliance list: ISO 9001:2015, RoHS, REACH. Exact document sets are confirmed on the order.
Quotation
- The fastener family (DIN 6916 Plain Chamfered Washers) plus the standard designation from your drawing — DIN / ISO / JIS / ASTM / ANSI, or a drawing for custom parts.
- Size (diameter and length), thread type (metric or inch), property class or grade, and coating or finish.
- Quantity per size and your target delivery date.
- Destination country, and any required documents (for example a mill test certificate) so the quote includes them.
Sample & supply
Minimum order quantity is 10,000 pieces. Stock items run 3–7 days. Quantities or variants outside the standard range are confirmed at quotation.
Storage & shipping
Parts are packed for export and shipped factory-direct to buyers in Europe, Asia, the Americas and the Middle East. Store fasteners dry and protected until installation, and keep coated parts in their packaging until use; specific packing and preservation requirements can be stated on the order and confirmed at quotation.
Frequently asked questions
Are DIN 6916 and EN 14399-6 washers interchangeable?
On the collected geometry, effectively yes for the shared sizes: compare the two ladders in this catalog and the hole, outside-diameter and thickness figures match at every size from M12 through M36 (the M27 washer, say, is a 28–28.52 mm bore on a 50 mm outside diameter at 5 mm nominal in both tables). The differences live in the paperwork and the fine print — the EN standard is the current designation with a defined system-HV pairing to EN 14399-4 bolts, while DIN 6916 is the legacy German designation many mill drawings still call up — and the chamfer rows differ in presentation (the EN table splits e and c into min/max, the DIN table prints a single approximate chamfer). Order by the designation your drawing names; where a mixed set is proposed, confirm the pairing at quotation because neither collected table tabulates hardness or finish.
