Correlates specific plating thicknesses with performance outcomes in standard salt spray tests. 3. The Risk of Hydrogen Embrittlement
DIN 267 Part 9 utilizes a standardized coding system to describe the desired surface finish precisely. A typical designation looks like a combination of letters and numbers (e.g., A2F or A3K ). Code Position Base metal and coating metal A = Zinc (Zn), B = Cadmium (Cd) Second Digit (Number) Minimum coating thickness 1 = 3µm, 2 = 5µm, 3 = 8µm, 4 = 12µm Third Digit (Letter) Passivation, chromating, and color C = Yellow iridescent, F = Jet black, K = Clear 5. Testing and Quality Assurance
Provides details on the superseded status of the document. Frequently Asked Questions (FAQ) din 267 part 9 pdf
If you have searched for a , you are likely an engineer, quality manager, or procurement specialist trying to decipher the mechanical properties of a specific screw or bolt. However, there is a common pitfall: DIN 267 Part 9 has been withdrawn and replaced.
While general-purpose fasteners (e.g., property classes 8.8, 10.9, 12.9) lose strength at high temperatures, DIN 267-9 covers materials designed to retain mechanical integrity in environments ranging from approximately 300°C to over 600°C.
If you need the technical data originally found in DIN 267 Part 9, you must download (or later editions). This standard specifically covers: | Nut Property Class | DIN 267-9 (Old)
Full document previews and historical archives of the specification can be found on online repositories like the Antpedia DIN 267-9 PDF Registry or via the official publisher DIN Media . Core Scope and Engineering Field of Application
applied to mechanical fasteners like bolts and nuts. However, you should note that this standard is officially and has been superseded by international standards. Key Details
The DIN 267 series was extensive, covering many aspects of fastener technology. Here's a brief overview of some other parts of the series to help you understand where Part 9 fits in: A typical designation looks like a combination of
Electroplating is commonly used on fasteners to achieve two primary goals:
Professionals working with both German and international fastener specifications can use DIN 267 Part 9 as a reference point when translating requirements between older and newer standards.
Specifies minimum layer thicknesses (e.g., 3 µm, 5 µm, 8 µm) to ensure functional performance. It emphasizes that the coating must not cause the zero line of the thread tolerance to be exceeded (for bolts) or not attained (for nuts).
The dimensions and tolerances of the fasteners shall be in accordance with the relevant standards, such as DIN 13 and DIN 14.
For example, the code "A5m" specified a zinc coating (A) with a thickness of 15 μm (5) and a matte finish (m).
