Used in critical structural fasteners, engine components, or specialized assembly points where high shear stress and vibration are present.
The "exclusive" variant is evolving due to environmental regulations. Hexavalent chromium (CrVI) is facing a global phase-out. What does this mean for DIN 509E06X02?
The Deutsches Institut für Normung (DIN) is the German national standardization body. It develops and publishes standards for a wide range of products and services, contributing to quality, safety, and efficiency in industries both domestically and internationally. din 509e06x02 exclusive
The keyword refers to a highly specific mechanical engineering specification for a Type E relief groove (undercut) as defined by the German Institute for Standardization (DIN) . In precision manufacturing, these undercuts are essential for ensuring that mating parts—such as a shaft and a bearing—can fit perfectly against a shoulder without interference from the naturally occurring radius left by a cutting tool.
| Component | Meaning | Technical Implication | | :--- | :--- | :--- | | | Deutsche Institut für Normung | The standard originates from Germany, known for the most rigorous engineering protocols globally. | | 509 | Main series for electroplated coatings | Governs nickel, chromium, zinc, and copper plating on steel, copper, and aluminum. | | E | Electroplated deposit (Elektrolytisch abgeschieden) | Specifies that the coating is applied via electrolytic bath, not electroless or mechanical. | | 06 | Coating thickness in micrometers (µm) | Indicates a nominal thickness of 6 micrometers . | | X | Type of coating – Nickel-Chromium (with special layers) | Denotes a multilayer system, typically bright nickel plus a microporous or microcracked chromium top layer. | | 02 | Corrosion resistance severity code | Refers to a specific service condition (usually moderate industrial or indoor high-humidity). | | Exclusive | Non-standard additive or proprietary process | Suggests a deviation from the generic standard—often including a sealing layer, a specific passivation, or an anti-fingerprint treatment. | Used in critical structural fasteners, engine components, or
Adhering to such a stringent standard offers numerous benefits to manufacturers, customers, and end-users:
The specification refers to a standardized Type E relief groove (undercut) with a radius of 0.6 mm and a depth of 0.2 mm , primarily used in precision machining to ensure proper fitment and stress distribution in cylindrical parts. This specific configuration is "exclusive" to components that require a single machining surface, typically where a cylindrical shaft meets a flat shoulder but the shoulder itself does not undergo further finishing.
