Specifies minimum layer thicknesses (e.g., 3 µm, 5 µm, 8 µm) to ensure functional performance. It emphasizes that the coating must not cause the zero line of the thread tolerance to be exceeded (for bolts) or not attained (for nuts).

Fasteners must be baked at specific temperatures (usually between 180°C to 220°C) within a strict timeframe immediately after plating to drive out trapped hydrogen atoms. 4. Testing and Conformity din 267 part 9 pdf
