Self-Drilling Screws: Match Point, Length, and Driver
Match the screw point, diameter, length, head, and driver to the metal stack and approved fastening detail.
Stop if
- For this connection I have [metal stack and screw]. Is this the approved point and length, and do you want a washer head or another fastener here?
Watch out
- Do not use whatever screw is in your pouch, overrun the clutch, or leave points where they can damage insulation, wiring, or hands.
Check
- Identify the total metal thickness being joined
- Confirm screw type and allowed spacing
- Use the correct driver and clutch setting
- Keep the screw square to the surface
- Check that the point clears without hitting hidden work
