DIN 267 Part 9 was part of a larger series of German fastener standards, DIN 267, which covered "Screwed Fasteners and similar Parts" across multiple parts. Part 9 specifically focused on .

If a thick coating is necessary for harsh environments, the manufacturer must use a fundamental deviation (such as a 6e or 6f tolerance class for external threads) to provide "room" for the plating layer. 4. The Risk of Hydrogen Embrittlement

Uses an updated alphanumeric system indicating coating metal, thickness, and passivate layer Focuses heavily on baking hours

The standard has been partially superseded by DIN EN ISO 898 series, but many industries still reference DIN 267‑9 for legacy or special designs. To obtain the current version:

High-strength fasteners (typically those with a tensile strength of 1000 MPa or higher, such as property classes 10.9 and 12.9) are highly susceptible to hydrogen embrittlement during the acid pickling and electroplating processes.

The DIN 267 series was extensive, covering many aspects of fastener technology. Here's a brief overview of some other parts of the series to help you understand where Part 9 fits in: : It is frequently used for austenitic steel

If you are designing a high-temperature bolted joint:

A crucial point for anyone researching "DIN 267 Part 9 PDF" is to understand the standard's current status: and is no longer an active standard. This withdrawal is part of a broader effort to replace old national standards with up-to-date international (ISO) or European (EN) standards to promote global trade and consistency.

Applying a layer of metal onto a threaded fastener increases its physical dimensions. If the coating is too thick, the bolt may not fit into the corresponding nut or tapped hole.

This article provides a comprehensive overview of DIN 267 Part 9, its technical requirements, and its relationship with modern international standards like ISO 4042. What is DIN 267 Part 9? If you share with third parties, their policies apply

: Preventing rust and oxidation in atmospheric environments.

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 covers the following aspects:
