Oval Head Self Drilling Screw



Oval head Self Drilling Screw is also known as European standard DIN 7504Q. Oval heads provide a more decorative appearance compared to flat heads. The oval dome shape allows for countersinking into conical surfaces, unlike flat heads. An oval head can provide a cleaner look compared to pan or flat head styles when aesthetics are important.

The precise drill point cuts an accurate pilot hole and engages metal quickly without "walking" like some other tips.

Common applications include attaching wood siding, panels, or trim to steel framing.

Surface finishes like zinc plating, yellow zinc, and ruspert coating provide corrosion protection and ease of driving.
Proper screw length selection is important based on the thickness of material being fastened to ensure sufficient engagement into steel. Pre-drilling is typically not required due to the self-drilling tip. Slow drill speeds prevent damage.

  • Attach wood siding, wood panel & metal trim to steel studs.
