DIN 267 Part 9 is an essential German standard specifying mechanical properties for fasteners (bolts, screws, and studs) made of steel with reduced loadability due to their design or size. It is often referenced in conjunction with other fastener standards like DIN EN ISO 898. If you need the official PDF for engineering, quality control, or procurement, this post covers its scope, key requirements, and where to find the document.
To clarify the most common questions, here are straightforward answers:
.
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 din 267 part 9 pdf
The standard imposes strict rules based on the property class and hardness of the steel: Property Class ≤is less than or equal to
This standard was also cross-referenced with other essential regulations, such as several parts of (which defines metric ISO general-purpose screw threads) and DIN 50933/50941 (standards for thickness measurement of coatings). This network of standards helped create a comprehensive and reliable system for fastener technology.
Specific heat-treatment protocols required for high-tensile fasteners to prevent structural failure. 3. Dimensional Limits and Thread Tolerances DIN 267 Part 9 is an essential German
Assures that coated threads are interchangeable and usable.
A critical section of the DIN 267 Part 9 PDF addresses hydrogen embrittlement. This phenomenon occurs when atomic hydrogen enters high-strength steel during the acid pickling or electroplating process, leading to sudden, brittle failure under tensile stress. High-Risk Categories

| Nut Property Class | DIN 267-9 (Old) | ISO 898-2 (New) | Compatible Bolt Class | | :--- | :--- | :--- | :--- | | 04 | Yes (Low carbon steel) | No (Obsolete) | 4.6 | | 4 | Yes | Yes | 4.6 / 4.8 | | 5 | Yes | Yes | 5.6 / 5.8 | | 6 | Yes | Yes | 6.8 | | 8 | Yes | Yes | 8.8 | | 10 | Yes | Yes | 10.9 | | 12 | Yes | Yes | 12.9 |
DIN 267 Part 9 is a German national standard developed by the Deutsches Institut für Normung (DIN). It outlines the requirements for electroplated corrosion protection coatings on threaded steel fasteners. Scope and Application
Burnishing or thermal shock tests ensure the plated layer does not peel or blister under stress.
The DIN 267 Part 9 PDF standard has implications for both fastener manufacturers and users:
The standard covers the following aspects:
