DIN 7504M Cross Recessed Pan Head Drilling Screws
DIN 7504-M cross recessed pan head drilling screws are designed for applications where drilling and fastening need to be completed in one operation. Their pan head design provides a broad bearing surface, while the cross recess allows convenient installation with a matching driver bit. The integrated drill point eliminates the need for a separate drilling step when fastening suitable metal sheets and profiles.
We use professional cold heading and thread rolling machines to manufacture screws with consistent head geometry and thread accuracy. Together with controlled heat treatment and quality checks, these processes help us maintain reliable drilling performance and consistent product quality across different sizes.

Mechanical Property:
ISO 10666 Mechanical Property
ISO 10666 specifies the mechanical and functional requirements for heat-treated steel drilling screws with tapping screw threads. For DIN 7504-M cross recessed pan head drilling screws, these requirements are relevant to the strength of the screw body and the performance of the drill point during installation. Surface hardness, core hardness, case hardening depth and torsional strength help assess the screw’s resistance to wear and breakage, while drilling tests evaluate its ability to penetrate the specified material and form threads effectively.
