267 Part 9 Pdf: Din
According to DIN 267-9, electroplated coatings are applied by immersing parts in an aqueous solution with an electric current. This is distinct from hot-dip galvanizing, which uses molten zinc.
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).
: It establishes that electroplated coatings must not cause the zero line (theoretical limit) of the thread to be exceeded for bolts or not attained for nuts. Designation System
Techniques for verifying coating quality and thickness. din 267 part 9 pdf
It outlines how the electroplated layer affects the thread tolerances, ensuring that the "zero line" is not exceeded for bolt threads or attained for nut threads after coating .
While many legacy drawings, corporate parts catalogs, and maintenance manuals still explicitly reference "DIN 267 Part 9", the standard has been technically superseded. Transition to ISO 4042
Applies primarily to threaded fasteners (M1.6 to M36) and other mechanical parts receiving electrolytic metallic layers. Layer Thickness: According to DIN 267-9, electroplated coatings are applied
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:
The technical requirements in DIN 267-9 are closely aligned with international standards.
While many legacy blueprints, manufacturing routes, and supply chains still request a "DIN 267 part 9 pdf" or reference the standard directly, modern production facilities typically fulfill these orders using ISO 4042. ISO 4042 updates the passivation codes to reflect modern environmental regulations—such as Hexavalent Chromium (CrVI) restrictions like RoHS and REACH—and provides updated guidelines on avoiding hydrogen embrittlement. Where to Find and Download the PDF : It establishes that electroplated coatings must not
When working with industrial fasteners—specifically bolts, nuts, and screws—ensuring their longevity and functionality requires adhering to strict quality standards. (DIN 267-9) is a crucial German industrial standard that defines the technical delivery conditions for mechanical fasteners with electroplated coatings.
The minimum thickness at specified measurement points on the fastener (typically on the head or flats, avoiding the threads where pooling occurs). 3. Hydrogen Embrittlement Protection
