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. Hydrogen Embrittlement
No. Part 9 was for carbon/alloy steel. Stainless fasteners fall under DIN 267 Part 11 (now replaced by ISO 3506).
DIN 267 Part 9 is a standard that specifies the requirements for precision bolts, screws, and nuts with product grade A. These fasteners are typically used in applications where high precision and accuracy are required, such as in mechanical engineering, automotive, and aerospace industries. din 267 part 9 pdf
Your search for a is a sign that you are working with outdated technical data. While you can buy a historical copy for archival purposes, the smart engineering move is to download DIN EN ISO 898-2:2012 .
DIN ISO 4042 ("Fasteners — Electroplated coating systems"). Electroplating adds material
A major component of the standard is specifying the thickness of the metallic coating. It ensures that the coating provides adequate corrosion protection without interfering with the mechanical functionality of the fastener, particularly the thread assembly. 3. Thread Tolerance Positions (9f, 6g, H, G)
Using screws that comply with DIN 267 Part 9 offers several benefits, including: Stainless fasteners fall under DIN 267 Part 11
: Accompany high-tensile batches with a certificate of compliance confirming baking duration and temperature.
The standard defines how to handle threads. A critical aspect is that for bolt threads and H or G for nut threads apply prior to the application of the electroplated coating.
Professionals working with both German and international fastener specifications can use DIN 267 Part 9 as a reference point when translating requirements between older and newer standards.
: Coatings are identified by a code consisting of two capital letters and a number, indicating the metal type, minimum layer thickness, and degree of gloss/after-treatment. Current Status : This standard is superseded Replacement
