Din 267 Part 9 Pdf Online

is a withdrawn German technical standard that specified the delivery conditions for mechanical fasteners with electroplated coatings . It has been largely replaced by the international standard ISO 4042 . 🛠️ Technical Focus

Can be performed using destructive methods (like microscopic cross-sectioning) or non-destructive methods (such as magnetic induction or X-ray fluorescence).

: Accompany high-tensile batches with a certificate of compliance confirming baking duration and temperature.

By understanding DIN 267-9, engineers and procurers can properly maintain and verify the quality of older fastener systems while referencing modern standards for new designs. din 267 part 9 pdf

: The coating must not peel or flake when subjected to burnishing or thermal shock tests.

Comprehensive Guide to DIN 267 Part 9: Technical Conditions for Electroplated Fasteners is a withdrawn German technical standard that specified

In practice, these requirements meant that for high-strength fasteners (property classes such as 10.9 and 12.9) and hardened parts exceeding 390 HV, the risk of hydrogen embrittlement could not be entirely ruled out. Consequently, such parts were electroplated only on express customer order and at the customer's responsibility.

It ensures that the plated thread does not exceed the zero-line (the maximum material limit of the standard thread class, usually 6g for bolts and 6H for nuts). 2. Hydrogen Embrittlement Risks

While the standard has been officially withdrawn and replaced by international standards such as , it remains a critical reference for legacy engineering projects, maintenance of older machinery, and specific industrial sectors that still cite it in technical drawings. Overview of DIN 267 Part 9 : Accompany high-tensile batches with a certificate of

: It ensures coatings don't exceed the "zero line" of a thread, preventing assembly jams.

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.
