The coating metal (e.g., A = Zinc, B = Cadmium, C = Nickel). The minimum layer thickness in micrometers (

DIN 267-9 was officially superseded in June 1992 and has been replaced by the international standard (and previously by DIN ISO 4042 ). This transition is a critical detail because using the old, withdrawn standard can have serious consequences. The mechanical and technical requirements of the new ISO standard are not identical to the old DIN version. For instance, DIN standard nuts often do not meet the proof load and hardness values required by the current ISO standard. din 267 part 9 pdf

The DIN 267 Part 9 standard serves as a foundational text for understanding the interplay between chemistry and mechanical engineering in fastening technology. While is the modern equivalent for new designs, the legacy DIN standard remains vital for interpreting historical technical drawings, calculating thread clearance tolerances, and understanding baseline protocols for hydrogen de-embrittlement baking.

For anyone looking to download a DIN 267 Part 9 PDF, it is vital to understand its current regulatory status. This transition is a critical detail because using

: The standard mandates specific baking (hydrogen de-embrittlement) heat treatments shortly after plating to drive out the trapped hydrogen. 3. Corrosion Resistance (Salt Spray Testing)

One of the most critical aspects of DIN 267 Part 9 is its addressing of hydrogen embrittlement. During the acid pickling and electroplating processes, atomic hydrogen can penetrate the steel matrix of high-strength fasteners. Under tensile stress, this can lead to catastrophic, brittle failure.

The primary objective of DIN 267 Part 9 is to define the characteristics of electrodeposited coatings applied to fasteners with ISO metric screw threads. The standard ensures that after the plating process, the fasteners still fit into their corresponding tapped holes or nuts while providing the intended level of corrosion protection. The standard covers several critical parameters: before and after coating. Layer thickness requirements for different thread pitches.

To define the technical requirements for fasteners that have been electrolytically (galvanically) coated to provide corrosion protection or specific functional properties.
