DIN 267 is a multi-part German standard covering technical delivery conditions for mechanical fasteners. Part 9 specifically addresses mechanical properties of fasteners made of steels with specified elevated temperature properties. In simpler terms, it tells engineers and manufacturers how bolts, screws, and studs must perform when the heat is on—literally.
While general-purpose fasteners (e.g., property classes 8.8, 10.9, 12.9) lose strength at high temperatures, DIN 267-9 covers materials designed to retain mechanical integrity in environments ranging from approximately 300°C to over 600°C.
DIN 267 Part 9 defines cleaning and sterilization requirements for process equipment used in food, beverage and pharmaceutical production. Following this part helps manufacturers reduce contamination risk, meet regulatory expectations, and design equipment that’s easier and safer to clean — saving time and cutting costs.
While a “DIN 267 part 9 PDF” is not freely distributable, understanding its scope helps engineers choose the right fastener for hot, demanding environments. The standard bridges the gap between general-purpose fasteners and exotic high-temperature alloys, ensuring safety and performance where temperatures rise. For current work, always check the latest EN or ISO equivalents, and purchase the official document from a recognized standards body.

If you are looking for the official PDF or specific details regarding this norm, use this overview regarding its function, contents, and current standing in modern engineering. 📄 Overview of DIN 267 Part 9
The Deutsches Institut für Normung (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.
Key Objective: To prevent the coating from making the threads too thick, ensuring the fasteners still screw together properly without sacrificing corrosion resistance.
Crucial Risk Management: Regulates baking processes after plating to minimize the risk of hydrogen embrittlement, which is highly dangerous for high-tensile fasteners. 🛠️ Key Technical Contents
If you analyze the contents of the document, it generally outlines several critical parameters:
Layer Thickness: Prescribes how thick the protective plating (such as zinc or cadmium) can legally be on the external and internal threads.
Dimensional Impact: Focuses on the "fundamental deviation" of the screw threads. Thick electroplating can exceed tolerance limits, causing parts to jam during assembly.
Corrosion Protection Testing: Details the duration and conditions for standard testing (like salt spray tests) to prove adequate protection against rust.
Designation System: Explains the specific letter and number codes used in blueprints and orders to demand exactly which coating process and thickness are required. ⚠️ Important: Current Status & Modern Replacements

Title: DIN 267 Part 9 PDF – Mechanical Properties of Fasteners with Reduced Loadability
Introduction
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.
Scope of DIN 267 Part 9
This part of the DIN 267 series applies to threaded fasteners where the shank diameter is less than the nominal thread diameter (e.g., reduced shank bolts) or where other design features reduce load-bearing capacity. It defines:
Key Classes & Properties
The standard covers property classes such as 04.8, 06.8, 08.8, 10.9, and 12.9 with modifications for reduced loadability. For example:

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:
Quick Summary Table
| Feature | Detail | |---------|--------| | Standard | DIN 267 Part 9 (Ausgabe 1983-12 or later) | | Title | Mechanical properties of fasteners with reduced loadability | | Applies to | Steel bolts/screws with reduced shank diameter | | Key tests | Tensile strength, hardness, proof load | | Superseded by | Partially by DIN EN ISO 898, but still active for special designs |
Final Tip
Before designing with reduced‑shank fasteners, check if DIN EN ISO 898‑1 covers your case. For non‑standard reduced sections, always reference DIN 267‑9 in your documentation and obtain the latest official PDF to ensure legal compliance and safety.
In the world of mechanical engineering and bolted connections, precision is everything. Standards like the DIN 267 series have long provided the backbone for fastener quality and safety. Among these, DIN 267 Part 9 holds a specialized but critical role: defining requirements for mechanical fasteners intended for use at elevated temperatures.
DIN 267 Part 9 (often written as DIN 267-9) is a German standard that specifies the technical delivery conditions for fasteners—such as bolts, screws, studs, and nuts—made from non-ferrous metals.
While other parts of the DIN 267 series focus on steel fasteners, Part 9 is specifically critical for industries requiring corrosion resistance, non-magnetic properties, or specific aesthetic qualities, such as marine engineering, chemical processing, and electronics.
A: No, it is not illegal, but it is not "presumed compliant" with EU Machinery Directive 2006/42/EC. If your product fails and you used a withdrawn standard, you will lose liability lawsuits.
In the world of mechanical engineering and fastening technology, standards are the silent guardians of safety. Among the labyrinth of German Institute for Standardization (DIN) norms, DIN 267 Part 9 holds a critical, yet often misunderstood, position.
If you have searched for a DIN 267 Part 9 PDF, you are likely an engineer, quality manager, or procurement specialist trying to decipher the mechanical properties of a specific screw or bolt. However, there is a common pitfall: DIN 267 Part 9 has been withdrawn and replaced.
This comprehensive article will explain what DIN 267 Part 9 was, why you cannot find an official "active" PDF, which standard replaced it, and how to access the technical data you need for high-strength fasteners.
