| Designation | Head Form | Key Characteristics | | :--- | :--- | :--- | | | Hexagon head with a flange (washer face) | Allows for high torque transmission, and the integrated flange distributes the load. | | DIN 7504 M | Pan head (cylindrical raised head) | Often features a cross recess (Phillips or Pozidriv) for general-purpose applications. | | DIN 7504 O | Countersunk flat head | Designed to sit flush with or below the material's surface for a smooth finish. | | DIN 7504 P | Pan head with a cross recess | A common general-purpose head style for light to medium-duty fastening. |

If the thickness of the substrate exceeds the length of the unthreaded drill point (

When designing structural components or sourcing manufacturing parts, relying on secondary data tables can lead to compliance issues. To ensure exact tolerances, engineers should source an official, updated version of the standard. din 7504 k standard pdf

In modern manufacturing, the German DIN standards are frequently updated to align with the International Organization for Standardization (ISO). has been officially replaced by ISO 15480 . | | DIN 7504 O | Countersunk flat

Maximum material thickness limits for each screw diameter.

The standard also defined the maximum drilling capacity (f) for each screw size. For example, an ST 3.5 DIN 7504 K screw can reliably drill through a total material thickness of up to 2.25 mm, while a larger ST 5.5 can handle up to 5.25 mm.

The thickness of the hexagonal head excluding the flange.

While technically superseded, the DIN 7504 K and ISO 15480 standards are functional equivalents. The original German standard.
