  • You are looking for a #8 I believe. In your Hardware store pick up a box carry it to the screw aisle and verify to be sure it could be #6 neither are expensive .50 for a pack each.

Most likely 8-32, possibly 6-32. Watch out, 8-32 is fine thread.

The -32 is intentional as it assures enough thread engagement.

Make sure you are hanging your fan by more than just a couple #8 screws!
