DIN 267 Part 9 is a historical German technical standard that specifies the delivery conditions for mechanical fasteners with electroplated coatings, primarily bolts, screws, and nuts. While it has been largely superseded by the international standard ISO 4042, it remains a critical reference in legacy engineering documentation and for specific fastener replacements. Scope and Application
Purpose: To define the technical requirements for fasteners that have been electrolytically (galvanically) coated to provide corrosion protection or specific functional properties.
Applicability: It applies to threaded steel fasteners with metric ISO threads, as well as some non-threaded parts like washers and pins.
Main Focus: The standard is primarily concerned with coating thickness, its measurement, and the impact of these layers on thread tolerances. Key Technical Requirements
Coating Thickness: 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).
Dimensional Accuracy: Fasteners must comply with thread tolerance positions (typically 6g, 6f, or 6e for bolts and 6H or 6G for nuts) before the coating is applied.
Hydrogen Embrittlement: For high-strength fasteners (typically property class 10.9 and above), the standard includes provisions to minimize the risk of hydrogen embrittlement caused by the plating process.
Surface Designations: Uses a coding system consisting of letters and numbers to specify the coating metal, thickness, and finish (e.g., A2K for a zinc coating with 5 µm thickness and a glossy chromated finish). Current Status and Alternatives
Superseded By: DIN 267-9 was officially replaced by DIN ISO 4042 (later ISO 4042:2022).
Documentation: You can find digital copies or historical versions through standard distributors like the DIN Media Shop or Standards.ie.
Reference Materials: For a technical breakdown of how these coatings interact with modern fastener grades, specialized manuals from WÜRTH Industrie are helpful resources.

DIN 267 Part 9 is a critical technical standard for the manufacturing and quality assurance of fasteners, specifically focusing on electroplated coatings
. It provides the technical conditions of delivery for components like bolts, screws, and nuts that require a galvanic finish. Core Focus of DIN 267-9
The standard's primary mission is to manage how protective coatings affect the physical fit and performance of threaded fasteners. Layer Thickness Specification
: It defines the permissible thickness of electroplated layers to ensure they provide adequate corrosion protection without interfering with the fastener's assembly. Thread Tolerance Management
: A major focus is ensuring that the coating does not cause a bolt thread to exceed its zero line or a nut thread to fall below it. It references
for metric screw thread tolerances (specifically positions g, f, and e for bolts; H and G for nuts). Technical Conditions
: It acts as a bridge between raw manufacturing and the finished, plated product, setting the "rules of engagement" for how these coatings are applied, tested, and designated. Why This Standard Matters (The "Interesting" Bit)
In the world of precision engineering, adding even a few microns of material (like zinc or nickel) can be the difference between a bolt that spins freely and one that seizes. DIN 267-9 ensures that: Zero-Line Integrity
: The "zero line" is the theoretical boundary of a thread. If a coating is too thick, the bolt won't fit into the nut. DIN 267-9 mandates that the coating must not push the bolt thread beyond this limit. Harmonization
: It works in tandem with other parts of the DIN 267 series, such as Part 5 for acceptance inspections Part 19 for surface discontinuities Modern Replacement
: While still referenced in many legacy projects, this standard has largely been superseded by
, which is the current international benchmark for electroplated coating systems on fasteners. Accessing the Document While the official, paid version is available through the DIN Media portal

DIN 267 Part 9 (or DIN 267-9) defines the technical delivery conditions for mechanical fasteners with electroplated coatings
. It establishes the standards for how coatings—such as zinc or cadmium—should be applied, measured, and designated on bolts, screws, and nuts. Core Content of DIN 267 Part 9
The standard focuses on ensuring that the addition of a protective layer does not interfere with the mechanical function of the fastener.
Applies primarily to threaded fasteners (M1.6 to M36) and other mechanical parts receiving electrolytic metallic layers. Layer Thickness:
Specifies minimum required thicknesses and how they must be measured at specific points on the fastener. Thread Tolerances:
Ensures that the coating thickness does not cause the thread to exceed its zero line (maximum material limit), which would prevent proper assembly. Designation Code System: Uses a code (e.g., A2K) to describe the coating: First Letter: The coating metal (e.g., A for Zinc). The minimum layer thickness (e.g., 2 for Second Letter:
The degree of gloss and any after-treatment like passivation or chromating. Hydrogen Embrittlement:
Includes guidelines for baking (heat treatment) to reduce the risk of hydrogen-induced brittle fracture in high-strength fasteners after plating. Status and Replacements

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

DIN 267 is a multi-part German standard covering technical delivery conditions for mechanical fasteners. Part 9 specifically addresses mechanical properties of fasteners made of steels with specified elevated temperature properties. In simpler terms, it tells engineers and manufacturers how bolts, screws, and studs must perform when the heat is on—literally.
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.
