3. Applications:
Phillips pan head self drilling screws have a sheet metal thread with a self driller cutting (TEK) point to pierce through 20 to 14 gauge metals.
Similar to sheet metal screws, but they have a drill-shaped point to cut through sheet metal or steel which eliminates the need for drilling a pilot hole. These self-drilling screws are designed for use in soft steel or other metals.Self-drilling screw points are numbered from 1 through 5, the larger the number, the thicker metal it can go through without a pilot hole. A 5 point can drill a 0.5 in (13 mm) of steel, for example.
Self-Drilling Screws are also commonly called:
• Tek Screws
• Pro Points
• Self Tapping Screws
• Drill Bit Tip Screws

5. Self-Drilling Screw Troubleshooting Guide
| Split at point (web) | Excessive force (feed) applied while drilling | Reduce application force |
| Outer corners worn or melted | Drill RPM (cutting speed) too high | Use slower motor or partial trigger pull |
| Cutting edges chipping or breaking | Excessive force (feed) applied while drilling | Reduce application force |
| Point melted or diameter significantly reduced | Work material too hard | Confirm work material specs |
| Insufficient chip clearance | ||
| Excessive force (feed) applied while drilling | Choose screw with longer pilot section | |
| Reduce application force | ||
| Screw spins without drilling a hole | Drill motor set on reverse | Check motor direction |
| Work material too hard | Confirm work material specs | |
| Drill point blunted by handling | Inspect unused drill points for possible damage (from handling) |
