DIN 7504N Cross Recessed Pan Head Drilling Screws
DIN 7504-N cross recessed pan head drilling screws are suitable for fastening thin metal sheets, steel profiles and other compatible metal components. Their integrated drill point allows the screw to penetrate the material and form a mating thread during installation, reducing the need for separate drilling and tapping operations. This makes them practical for sheet metal assembly and light steel construction where installation efficiency is important.
The pan head sits above the material surface and provides a broad bearing area around the screw hole. Combined with the cross recess, this head style is suited to applications requiring straightforward driver access and a raised-head finish. The appropriate screw size and drill point capacity should be selected according to the material thickness and fastening requirements.

Mechanical Property:
ISO 10666 Mechanical Property of Self Drilling Screw
DIN 7504-N cross recessed pan head drilling screws require sufficient hardness and torsional strength to withstand the stresses generated during installation. The drill point must penetrate the specified metal sheet, while the tapping threads form a mating thread without becoming deformed. These properties are particularly important when the screws are used in sheet metal assembly and light steel structures, where reliable drilling and fastening performance are essential.
For heat-treated steel drilling screws, ISO 10666 specifies requirements for surface hardness, core hardness, case hardening depth, torsional strength and functional performance. These properties help assess the screw’s resistance to breakage during installation and its ability to complete drilling and thread formation under the specified test conditions.
