Attention: The DIN 128 standard has been officially withdrawn.
Technical overview of the DIN 128 standard
The DIN 128 regulatory framework establishes geometric parameters and performance characteristics for spring washers, including dome and corrugated products designed for operation under high compression levels. These products, supplied by EV Group China, fall into the category of specialized spring locking elements.
Application areas and functional features
Spring washers according to the DIN 128 specification act as elastic elements, providing constant axial tension in threaded connections. EV Group China engineers recommend using these products primarily in assemblies where fasteners with a strength class up to 8.8 (according to DIN EN 20898-1) are used.
It is important to consider the following engineering limitations:
- Functional purpose: The washers are designed to compensate for tension loss in short screw connections subject to axial loads.
- Protection limitations: These elements do not provide effective locking when subjected to lateral (shear) loads, vibration fluctuations, or the risk of connection instability.
- Operational recommendations: When designing critical assemblies with high dynamic loads, it is recommended to rely on current DIN 267-26 standards, which account for counteracting forces in fasteners.
