Din 5464 Standard Pdf ((top)) May 2026
The DIN 5464 standard, titled "Straight-sided splines - Heavy series," is the current German technical specification for high-torque shaft-hub connections. This heavy-duty series features more teeth than standard profiles (like DIN ISO 14), allowing for greater load capacity and thinner hub walls. Key Specifications
Application: Fixed and moving shaft-hub connections requiring high torque transmission without radial expansion. Design: Straight-sided flanks with a 0° pressure angle.
Centering: Primarily flank-centered, but can be configured for diameter centering. Document Length: 9 pages for the current 2010 edition. Current Status and Availability
The standard is currently active. The most recent version was published in March 2010 (DIN 5464:2010-03), superseding the original September 1965 version.

Key Technical Features
The standard is favored in specific heavy-duty sectors because of its inherent design advantages:
- Involute Flanks: The teeth are shaped like the involute of a circle (similar to gear teeth). This shape ensures that when the shaft and hub are under load, the forces are transmitted radially. This creates a "centering" effect, significantly reducing shear stress on the teeth compared to straight-sided splines (like DIN 5462).
- Centering Mechanism: DIN 5464 connections are typically centered on the flanks of the teeth. This allows for self-centering during assembly, ensuring even distribution of load across all teeth.
- High Torque Capacity: Because the load is shared across multiple teeth with a robust root design, these connections can transmit significantly higher torque than keyed connections of similar diameter.
Step 4: Inspection
Manufacturers use go/no-go plug gauges and double flank rolling testers to verify splines. The tolerances for these gauges are also specified in Annex A of the DIN 5464 standard.

Option 3: Beware of "Free PDF" Websites
Sites claiming "DIN 5464 standard PDF free download" often host malware, watermarked unofficial copies, or scanned versions of the long-withdrawn 1986 edition. These cannot be trusted for manufacturing. Involute Flanks: The teeth are shaped like the

Common Pitfalls
- Using an outdated edition or a partial copy that omits amendments.
- Misinterpreting normative references — some requirements may be specified in another standard.
- Treating the standard as optional rather than a legally and commercially binding reference when cited in contracts.

How to Reference DIN 5464 on a Drawing (ISO 129-1)
If you are writing a purchasing spec or drawing, here is the correct way to call out a DIN 5464 nut:
Example: Hexagon flange nut – DIN 5464 – M12 x 1.5 – 10 – A3C
- M12 x 1.5 = diameter and fine pitch
- 10 = Property class (strength)
- A3C = Coating (zinc plating with Cr(VI)-free passivation)
Important: If you are working in an international context, check if the customer will accept a non-ISO standard. Some global OEMs strictly forbid DIN-only standards. In that case, you may need to specify fine-pitch flange nuts using a custom drawing reference, not a standard number.
