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: While still referenced in many legacy projects, this standard has largely been superseded by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 is a standard established by the German Institute for Standardization ( ) that defines the
technical delivery conditions for mechanical fasteners with electroplated coatings Key Specifications
: It applies primarily to threaded fasteners like bolts and nuts but can extend to the entire range of mechanical fasteners. : The standard is mainly concerned with specifying layer thicknesses , their designation codes, and testing methods. Thread Tolerances
: It establishes that electroplated coatings must not cause the zero line (theoretical limit) of the thread to be exceeded for bolts or not attained for nuts. Designation System
: Coatings are identified by a code consisting of two capital letters and a number, indicating the metal type, minimum layer thickness, and degree of gloss/after-treatment. Current Status : This standard is superseded Replacement
: It has been largely replaced by international standards, specifically DIN EN ISO 4042 Compatibility
: Despite being superseded, many technical manuals and legacy specifications still refer to DIN 267 Part 9 for historical compliance or specific electroplating requirements.

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

To understand the document you are searching for, we must look at the history. DIN 267 was a foundational standard for "Mechanical fasteners – Technical delivery conditions." It was split into several parts, with Part 9 specifically covering:
"Mechanical properties of fasteners made of steel with specified property classes – Part 9: Nuts and mating fasteners."
In practical terms, DIN 267 Part 9 defined the relationship between screws and nuts. It dictated how a nut (strength class) must match a bolt (property class) to ensure that the thread would strip before the bolt broke—a safety feature known as "over-torque protection."

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: Scope : The standard defines the scope of
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
