DIN 267 Part 9 is a standard that outlines the technical delivery conditions for mechanical fasteners with electroplated coatings, primarily focusing on bolts, screws, and nuts . It provides essential specifications for layer thickness, thread tolerances after plating, and testing methods to ensure fasteners maintain their mechanical integrity while gaining corrosion resistance . Key Technical Specifications

Layer Thickness: The standard is primarily concerned with defining and testing the thickness of electroplated layers . This is critical because excessive coating can interfere with thread fit . Thread Tolerances:

It specifies that coatings must not cause the thread dimensions to exceed the "zero line" for bolt threads or fail to reach it for nut threads .

Basis for these thicknesses is grounded in ISO metric screw thread tolerances (DIN 13), specifically positions for bolts, and for nuts .

Designation Code: Plating is often identified by a three-part code: Coating Metal: A capital letter (e.g., A for Zinc) . Minimum Thickness: A number representing the layer depth .

Finish & After-treatment: A capital letter for gloss degree or chromating . Scope and Applications

Fastener Types: While mainly for bolts and nuts, it applies to various mechanical fasteners requiring electroplating .

Material Compatibility: It is frequently used for austenitic steel grades to bolster corrosion resistance in harsh environments .

Standard Status: Note that DIN 267-9 has been widely superseded by DIN ISO 4042 . Engineers often refer back to Part 9 for legacy specifications or specialized technical delivery conditions . Critical Considerations

If a specific, non-standard plating thickness is requested, it may require a larger "fundamental deviation" during manufacturing. This can potentially weaken the pull-out resistance of the screw/nut assembly if not carefully calculated .
