For current projects, you should seek out ISO 4042 for the latest plating standards. Summary Table: DIN 267-9 Key Information Standard Number DIN 267 Part 9 / DIN 267-9 Topic Mechanical Fasteners: Electroplated Coatings Core Content Layer thickness, Testing, Thread Tolerances Primary Scope Bolts & Nuts (Zinc/Cadmium Plating) Status Superseded by DIN EN ISO 4042
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.
The thickness of the electroplated layer directly correlates with how well the fastener resists rust and corrosion. DIN 267 Part 9 classifies coatings based on:

While DIN 267 Part 9 is no longer in force, its legacy lives on in the modern fastener industry. Its technical framework directly influenced the development of the current international standard, ISO 4042. For professionals needing the specific 1979 document, it can still be obtained from official standards archives. However, for all practical purposes of design and quality assurance, .
: 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
| Code Part | Description | Example | |-----------|-------------|---------| | First: Coating metal (a capital letter) | Identifies the metallic coating applied | A = Zinc, C = Copper, E = Nickel | | Second: Minimum layer thickness (a number) | Specifies coating thickness in micrometers | 3 = 8 μm, 5 = 15 μm | | Third: Degree of gloss and after-treatment (a capital letter) | Indicates appearance and passivation | A = mat, B = bluish iridescent | For current projects, you should seek out ISO
In the world of precision engineering, adding even a few microns of material (like zinc or nickel) can be the difference between a bolt that spins freely and one that seizes. DIN 267-9 ensures that: Zero-Line Integrity

High-strength fasteners (typically those with a tensile strength of 1000 MPa or higher, such as property classes 10.9 and 12.9) are highly susceptible to hydrogen embrittlement during the acid pickling and electroplating processes. DIN 267 Part 9 classifies coatings based on:

This standard specifies mechanical properties, testing, and marking requirements for steel bolts, screws, and studs with – meaning the shank diameter is intentionally smaller than the nominal thread diameter (waisted or reduced shank) to control elongation, fracture location, or energy absorption under tensile load.
