Electroplated Cadmium (Note: Often restricted in modern applications due to environmental regulations) 3. Thread Tolerance and Coating Thickness

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

For steel screws and bolts with (approximately corresponding to property classes above 10.9) and hardness ≥ 300 HV , DIN 267 Part 9 required appropriate heat treatment (tempering) according to DIN 898 Part 1 to minimize embrittlement risk. din 267 part 9 pdf

For the official, verifiable PDF, you should purchase it from authorized distributors:

: 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 High-Risk Categories For steel screws and bolts with

It references various procedures for measuring thickness, including microscopic measurement and the jet method. Relationship to Modern Standards

| 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 | Many older technical blueprints

Despite being superseded, legacy standards remain active in heavy industries, aerospace, and automotive manufacturing.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
