What Are The DIN Standards For Fasteners?

DIN (Deutsches Institut für Normung), which translates to the German Institute for Standardization in English, is responsible for developing and publishing various industrial and technical standards, including those for fasteners. DIN standards for fasteners cover a wide range of specifications for screws, bolts, nuts, washers, and other threaded and non-threaded fasteners. These standards are widely used in Germany and often adopted or referenced in other countries.

As a professional fastener supplier, Xinchi Fastener Company is glad to share some common DIN standards for fasteners.

DIN 931/933 – Hexagon head bolts with partial threads (ISO 4014/4017)

DIN 934 – Hexagon nuts (ISO 4032)

DIN 125 – Flat washers (ISO 7089)

DIN 912 – Socket head cap screws (ISO 4762)

DIN 985 – Nylon insert lock nuts (ISO 10511)

DIN 6921 – Hexagon flange bolts (ISO 8102)

DIN 7991 – Countersunk (flat) head screws (ISO 10642)

DIN 976 – Threaded rods (studs) (ISO 976)

Please note that the above standards are often harmonized with ISO (International Organization for Standardization) standards, which means they share similar specifications. DIN standards are widely used in Germany and Europe, but ISO standards are more commonly used on a global scale.

When using DIN standards for fasteners, it’s essential to check the specific DIN standard to ensure you have the correct information and dimensions for the type of fastener you are using.
