Metal Screw Drilling Guide

  • Start Slow to Seat the Screw
    Begin each hole at low drill speed so the bit won’t wander and the screw head seats cleanly into the metal.
  • Control Drill Speed to Protect Tips
    Our premium self-drilling screws have hardened tips, but running your drill too fast still overheats and dulls them—keep drill speed moderate throughout.
  • Maintain Alignment and Let the Bit Do the Work
    Hold the drill square to the surface with firm (not excessive) pressure.
  • Increase Speed Once Seated
    After the threads bite, you can safely ramp up for a quick, clean drive-through of the sheet.
  • Ensure Proper Washer Seal
    Stop driving as soon as the rubber washer is snug against the metal. Over-compressing deforms the washer and can compromise the watertight seal.
  • Inspect Your Work
    After a few screws, double-check for uniform depth, intact washer seals, and no stripped heads; adjust technique if anything looks off.
