Understanding DIN 7504 K Standard for Self-Tapping Screws
The DIN 7504 K standard specifies the dimensions, mechanical properties, and technical requirements for hexagon head self-drilling screws with a collar (also referred to as a flange). These screws are designed to drill their own pilot hole and form their own mating thread in a single operation, typically used for joining metal-to-metal or metal-to-wood. Key Specifications of DIN 7504 K The standard defines specific physical parameters for various screw sizes (ST 3.5 to ST 6.3): Head Style : Hexagon head with a built-in flange/collar. Material : Generally case-hardened steel (560 HV) or stainless steel (A2/A4). Dimensions : d (Thread size) : Ranges from ST 3.5 to ST 6.3. k (Head height) : Varies by size, e.g., ST 4.8 has a max height of 4.45 mm. s (Wrench size/SW) : Common sizes include 5.5 mm (for ST 3.5) and 8 mm (for ST 4.8). dc (Flange diameter) : Maximum diameter of the integrated washer/flange.

A Guide to DIN 7504 K: The Self-Drilling Standard for Metalwork If you are in construction or heavy metal fabrication, you have likely encountered the term DIN 7504 K . While it sounds like a technical serial number, it is actually one of the most reliable standards for self-drilling screws with a hexagonal head. The primary advantage of a DIN 7504 K screw is its efficiency; it eliminates the need for pre-drilling pilot holes, allowing the fastener to drill, tap, and secure in one single motion. What is the DIN 7504 K Standard? DIN 7504 is the German standard (issued by Deutsches Institut für Normung ) that governs self-drilling tapping screws. The designation specifically refers to the head style: a hexagonal head with an integrated flange or collar. ISO Equivalent : The international equivalent is Key Features : These screws typically feature a "drill point" tip capable of piercing sheet metal or heavy profiles up to several millimetres thick without prep.
