If you are looking for the official PDF or specific details regarding this norm, use this overview regarding its function, contents, and current standing in modern engineering. 📄 Overview of DIN 267 Part 9

The Deutsches Institut für Normung (German Institute for Standardization) developed this document to regulate the post-manufacturing electroplating of standard fasteners like bolts, screws, and nuts. Focus: Electroplated coatings on threaded fasteners.

Key Objective: To prevent the coating from making the threads too thick, ensuring the fasteners still screw together properly without sacrificing corrosion resistance.

Crucial Risk Management: Regulates baking processes after plating to minimize the risk of hydrogen embrittlement, which is highly dangerous for high-tensile fasteners. 🛠️ Key Technical Contents

If you analyze the contents of the document, it generally outlines several critical parameters:

Layer Thickness: Prescribes how thick the protective plating (such as zinc or cadmium) can legally be on the external and internal threads.

Dimensional Impact: Focuses on the "fundamental deviation" of the screw threads. Thick electroplating can exceed tolerance limits, causing parts to jam during assembly.

Corrosion Protection Testing: Details the duration and conditions for standard testing (like salt spray tests) to prove adequate protection against rust.

Designation System: Explains the specific letter and number codes used in blueprints and orders to demand exactly which coating process and thickness are required. ⚠️ Important: Current Status & Modern Replacements

The DIN 267 Part 9 standard historically provided the technical conditions of delivery for mechanical fasteners (bolts, screws, and nuts) specifically regarding electroplated coatings. While widely cited in legacy engineering documents, this standard is now withdrawn and has been replaced by international equivalents. 🛠️ Purpose and Scope

DIN 267-9 defined the requirements for fasteners that undergo galvanic (electroplated) treatments. Its primary focus included:

Thread Tolerances: Specifying how plating thickness affects the dimensional limits of metric threads.

Surface Quality: Guidelines for the finish and integrity of the coating. The DIN 267 Part 9 standard dictates the

Property Retention: Ensuring the electroplating process did not compromise the mechanical properties of the base metal. 🔄 Current Status and Replacements

The DIN 267 Part 9 standard is officially inactive. It has been superseded by international standards to harmonize manufacturing regulations globally. Former Standard Primary Replacement DIN 267-9:1979 Withdrawn (1992) DIN ISO 4042 (Fasteners - Electroplated coatings) DIN 267-9:1968 DIN ISO 4042 Technical manual

Here is the developed content for DIN 267 Part 9 (which is largely superseded by and related to DIN EN ISO 10642 and DIN EN ISO 4762 for socket head cap screws, but part 9 historically covers specific mechanical properties and requirements for mechanical fasteners with reduced loadability).

Scenario 3: You are writing a maintenance manual for a 1990s German machine.

  • Solution: Buy the historical DIN 267-9 PDF from DIN Media. Cite it as "Withdrawn, for reference only." Then convert the spec to ISO 898-2 for new spare parts.

Q2: Why do Chinese suppliers still send me DIN 267 Part 9 PDFs?

A: Because they use legacy catalogs. Insist they switch to ISO 898-2. Chinese standardization (GB/T) is based on ISO, not old DIN.

Technical Requirements Specified:

The document outlines specific criteria that manufacturers and buyers must agree upon:

  • Mechanical Properties: Tensile strength, yield strength, and hardness specific to softer non-ferrous metals.
  • Chemical Composition: Limits on alloying elements to ensure corrosion resistance.
  • Surface Finish: Requirements for coatings (e.g., chromium plating on brass) or bare finishes.
  • Testing Methods: How to verify the mechanical properties (e.g., tensile testing protocols for softer metals).
  • Marking: How the fasteners should be identified (often with property classes specific to non-ferrous metals).

Conclusion: Stop searching, start upgrading

Your search for a DIN 267 Part 9 PDF is a sign that you are working with outdated technical data. While you can buy a historical copy for archival purposes, the smart engineering move is to download DIN EN ISO 898-2:2012.

5. Related Standards (Alternatives)

If you are designing a new product, do not use DIN 267-9. Instead, refer to these modern equivalents:

  • ISO 16426: Fasteners – Non-ferrous metal fasteners (General requirements).
  • DIN EN ISO 3506: Mechanical properties of corrosion-resistant stainless steel fasteners.
  • DIN 267 Part 10: Technical delivery conditions for plastic fasteners (modern equivalent for non-metallics).

Technical Comparison: Old vs. New Classes

One reason engineers hunt for the old PDF is confusion over property classes. The tables have changed slightly.

Nut Property Classes (DIN 267-9 vs. ISO 898-2)

| Nut Property Class | DIN 267-9 (Old) | ISO 898-2 (New) | Compatible Bolt Class | | :--- | :--- | :--- | :--- | | 04 | Yes (Low carbon steel) | No (Obsolete) | 4.6 | | 4 | Yes | Yes | 4.6 / 4.8 | | 5 | Yes | Yes | 5.6 / 5.8 | | 6 | Yes | Yes | 6.8 | | 8 | Yes | Yes | 8.8 | | 10 | Yes | Yes | 10.9 | | 12 | Yes | Yes | 12.9 |

Note: Class 04 (very soft nuts) is no longer recognized in ISO standards. If your old drawing calls for DIN 267-9 Class 04, you must use Class 4 today.

3. Free Sources (Proceed with Caution)

You will find many websites offering a free DIN 267 Part 9 PDF. Warning: Many of these are: Scope : The standard defines the scope of

  • Scanned, illegible copies from the 1980s.
  • Incomplete (missing tables for M30+ diameters).
  • Pirated copies which are illegal to use for commercial certification (e.g., ISO 9001 audits will reject them).

Intended Scope:

This standard specifies mechanical properties, testing, and marking requirements for steel bolts, screws, and studs with reduced loadability – meaning the shank diameter is intentionally smaller than the nominal thread diameter (waisted or reduced shank) to control elongation, fracture location, or energy absorption under tensile load.
