In practice, these requirements meant that for high-strength fasteners (property classes such as 10.9 and 12.9) and hardened parts exceeding 390 HV, the risk of hydrogen embrittlement could not be entirely ruled out. Consequently, such parts were electroplated only on express customer order and at the customer's responsibility.
The standard relies on a concise alpha-numeric coding system to describe the desired plating material, required thickness, and degree of gloss. Din 267 | PDF - Scribd
: Older versions of these processes often used Hexavalent Chromium (the yellow/gold tint). Today, most industries avoid this due to toxicity, opting for "Clear" or "Blue" passivations. 🛡️ The Plating "Secret Code"
Understanding DIN 267 Part 9: Standards for Fasteners with Electroplated Coatings din 267 part 9 pdf
The standard typically covered fasteners made from:
The official publisher of German national standards. They offer historical and withdrawn standards for archival and legal reference.
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. In practice, these requirements meant that for high-strength
The surface finish of the fasteners shall be in accordance with the relevant standards.
You can legally purchase and download historical or equivalent PDF files from the official authorized distributor, DIN Media (formerly Beuth) .
The technical content of ISO 4042 builds directly on the framework established by DIN 267 Part 9. Understanding the original standard provides valuable insight into the rationale behind current electroplating requirements. Din 267 | PDF - Scribd : Older
Because DIN standards are copyright-protected documents, you cannot legally provide the actual PDF directly. Therefore, the content must serve as a that explains the standard in detail and directs the user to official sources.
Despite being superseded, legacy standards remain active in heavy industries, aerospace, and automotive manufacturing. Many older technical blueprints, engineering drawings, and spare parts catalogs finalized decades ago still explicitly reference "DIN 267-9." Consequently, suppliers must cross-reference the old standard to ensure they fulfill the historical requirements using modern equivalent coatings. How to Access the PDF Document
