Din 7504 K Standard Pdf !!hot!!

The DIN 7504 K standard specifies requirements for hexagon head self-drilling tapping screws equipped with a flange or embossed washer. While the original DIN standard has been officially withdrawn, it remains widely used in the industry and corresponds directly to the international standard ISO 15480. Technical Specifications Summary

Why use DIN 7504-K screws?

• Lower installation torque compared to thread-forming screws (e.g., DIN 7500)
• Reliable thread engagement in harder or brittle materials
• No pre-tapping – reduces assembly steps and cost
• Removable – unlike self-drilling screws, these are designed for threaded engagement, not just piercing.
