Din 267 Part 9 Pdf |top| -

Using DIN 267-9 ensures that all stakeholders—from design to procurement to quality control—are speaking the same language. Benefits include:

The maximum applicable coating thickness depends strictly on the pitch of the thread and the available fundamental deviation (clearance) of the specific tolerance class. DIN 267 Part 9 provides exact tables correlating thread pitch with permissible layer thicknesses, usually ranging from 3 µm to 15 µm. Hydrogen Embrittlement Risks

: The "zero line" is the theoretical boundary of a thread. If a coating is too thick, the bolt won't fit into the nut. DIN 267-9 mandates that the coating must not push the bolt thread beyond this limit. Harmonization

Applies primarily to threaded fasteners (M1.6 to M36) and other mechanical parts receiving electrolytic metallic layers. Layer Thickness:

The coating code is alphanumeric and indicates the coating metal (e.g., A = Zinc), the minimum layer thickness (e.g., 2 = 5 µm), and the passivating/chromating finish (e.g., C = yellow chromated). Current Status: DIN 267 Part 9 vs. ISO 4042 Using DIN 267-9 ensures that all stakeholders—from design

A: Generally, no. If the original design specified DIN 267-9, it likely required non-ferrous properties like non-magnetism or specific corrosion resistance that steel cannot provide without coating.

During the acid pickling (cleaning) and electroplating phases, atomic hydrogen ( Hydrogen Embrittlement Risks : The "zero line" is

The standard categorizes and establishes permissible limits for several types of surface imperfections that occur during the manufacturing process (such as forging, rolling, or heat treatment):

If you are manufacturing new components or updating procurement systems, it is highly recommended to reference instead of the obsolete DIN 267 Part 9 document. Testing and Quality Compliance

DIN 267-9 provided guidelines for fasteners made from non-ferrous metals (metals that do not contain iron, excluding stainless steel which has its own standards).
