The (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.
Guidelines for the finish and integrity of the coating.
DIN 267 is a multi-part standard issued by the Deutsches Institut für Normung (German Institute for Standardization) that outlines the technical delivery conditions for fasteners. Specifically, .

Details the duration and conditions for standard testing (like salt spray tests) to prove adequate protection against rust.
International standards portals often provide access to superseded European standards for tracking engineering lineages.
Correlates specific plating thicknesses with performance outcomes in standard salt spray tests. 3. The Risk of Hydrogen Embrittlement DIN 267 is a multi-part standard issued by
: It has been largely replaced by international standards, specifically DIN EN ISO 4042 Compatibility
The coating code is alphanumeric and indicates the coating metal (e.g., A = Zinc), the minimum layer thickness (e.g., 2 = 5 µm), and the passivating/chromating finish (e.g., C = yellow chromated). Current Status: DIN 267 Part 9 vs. ISO 4042
The baking process must begin as soon as possible, typically within 4 hours after electroplating, to effectively drive out the hydrogen before it causes micro-cracking. 4. Coating Designations and Coding System Share public link Details the duration and conditions

It applies to electroplated coatings such as zinc, cadmium, or other electro-deposited coatings on steel. Fastener Types: It covers screws, bolts, nuts, and washers.
