Din 7504 K Standard Pdf Fixed -
If you work with sheet metal, light-gauge steel, or die-cast components, you’ve likely encountered the need for a fastener that can tap its own thread without a separate tapping operation. That’s exactly where comes into play.
Note: For exact tolerances and intermediate lengths, procurement teams must consult official, current copies of the DIN 7504 K standard documentation. 3. Materials and Surface Finishes
The length of the unthreaded pilot point designed to evacuate metal shavings. DIN 7504 K Dimensional Matrix (Common Sizes): Nominal Thread Size (d) Width Across Flats (s) Head Height max. (k) Washer Diameter max. (dc) Drill Point Length max. (dp) Max. Drilling Capacity (Steel)
The strictly specifies the head geometry: a hexagonal drive paired with an integrated flange or collar, providing a broad load-bearing surface area without needing a loose washer. Technical Specifications and Dimensions din 7504 k standard pdf
Whether you require a like bimetal or zinc-plated carbon steel?
Usually made from steel, then case-hardened to achieve a surface hardness of approximately 560 HV. This ensures the tip remains sharp enough to drill through metal while the core remains strong.
