Din 50961 Fe Zn 8b May 2026

The technical specification DIN 50961 Fe/Zn 8b defines a specific electroplated zinc coating on iron or steel. This standard has largely been superseded by DIN EN ISO 2081

Technical Data Sheet: DIN 50961 Fe/Zn 8b

1. Definition The designation DIN 50961 Fe/Zn 8b describes a specific electroplated zinc coating on steel (or iron) parts. The standard (DIN 50961, now largely superseded by DIN EN ISO 4041 but still widely used in industry) defines the coating thickness, corrosion resistance requirements, and post-treatment (chromating).

DIN 50961 Fe Zn 8b is a technical shorthand used in engineering and manufacturing to specify a precise type of electroplated zinc coating on iron or steel parts. This code ensures that components—ranging from industrial fasteners to automotive brackets—possess the necessary corrosion resistance for their intended environment. Breakdown of the Code "Fe Zn 8b"

The string of characters acts as a "recipe" for the finisher:

• Interior or mildly corrosive environments (e.g., dry indoor use, low humidity).
• Automotive fasteners (screw, nuts, washers) for non-exterior chassis/body parts.
• Appliance hardware, electrical enclosures, stamped brackets.
• Where a thin, economic, and conductive coating is required.

: Ideal for small hardware such as screws, fasteners, and light switch plates. Thread Interference
