) are used for precision fasteners with tight thread tolerances. 4. Chromate Conversion Coating / Passivation ( B )

Historically governed by the German Institute for Standardization, the standard has largely been harmonized with international frameworks like DIN EN ISO 2081 . However, the legacy designation codes remain widely active across European supply chains, global blueprints, and manufacturing operations. Understanding the breakdown of this code ensures precise quality control, accurate procurement, and predictable component performance.

DIN (Deutsches Institut für Normung) 50961 is the German industrial standard that governs the requirements for electroplated zinc coatings on ferrous materials. It ensures that regardless of who manufactures a part, the coating will meet consistent quality levels regarding corrosion protection, adhesion, and appearance. 2. The Base Material: Fe stands for ) are used for precision fasteners with tight

Zinc coatings are widely used to protect iron and steel components from corrosion. The zinc layer acts as a sacrificial anode, corroding in place of the underlying metal to prevent damage. This process is known as cathodic protection. Zinc coatings are particularly effective in environments where the metal is exposed to moisture, salt, and oxygen. However, the legacy designation codes remain widely active

If you need to update technical drawings or choose an alternative coating, let me know. I can provide the or suggest a higher-corrosion alternative for harsher environments. Share public link
