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.
Because electroplating adds thickness, the screw threads are often manufactured to a tighter tolerance (6g) to allow for the added coating thickness without seizing, as mentioned in. 4. Code System for Designation
Can be performed using destructive methods (like microscopic cross-sectioning) or non-destructive methods (such as magnetic induction or X-ray fluorescence).
If you have specific fastener requirements for your project, let me know the , coating type , and expected environmental conditions so I can help you select the right DIN 267-9 specifications. Go to product viewer dialog for this item. M16 - 20pc Load Washers Zinc Plated Din 267
DIN 267 is a German standard series that covers safety and hygiene requirements for equipment and containers used in the food, beverage and pharmaceutical industries. Part 9 specifically addresses requirements for cleaning and sterilization of process equipment to ensure product safety, prevent contamination and enable effective hygienic design. Below is a concise, practical blog post you can publish. din 267 part 9 pdf
Electroplating adds material. Therefore, the thread tolerances must be managed properly. DIN 267-9 mandates that the dimensions of the threads after coating must meet the requirements of the underlying thread standards (e.g., ISO metric threads) at the maximum material condition (Go-gauge). 4.

The 1968 and 1979 versions are common historical references, but modern designs typically point toward the DIN Media library for the latest consolidated standards . Direct Downloads and Reference Sheets
Plated threads are checked using standard GO/NOT GO thread ring and plug gages to confirm that the coating has not oversized the component. To help find the exact file version you need, let me know:

Provides details on the superseded status of the document. Frequently Asked Questions (FAQ)
One of the most practical features of DIN 267 Part 9 was its for specifying electroplated coatings. This system allowed designers and engineers to call out specific plating requirements on drawings using a standardized three-part code.
Burnishing or thermal shock tests ensure the plated layer does not peel or blister under stress.
It is highly important for modern engineers and purchasing agents to note that . the main technical pillars include:
Consistent corrosion protection across different suppliers.
The official publisher of German national standards. They offer historical and withdrawn standards for archival and legal reference.
An important provision in DIN 267 Part 9 addressed . The standard specified that basic coating thickness and thread tolerances must comply with DIN 13, which covers ISO metric screw threads. This ensured that electroplated fasteners would still assemble properly with corresponding nuts or threaded holes despite the additional layer of metal.
