I am installing a ceiling fan in a newly built home. There's already a cover there and plate with wiring and two different types of screws in there. I wasn't sure which screws to use to hang up the fan.
I went with the smaller machine screws that are shown in the picture that are holding the fan up right now. I was just nervous because they were kind of small compared to the other longer ones I showed in the photo.
What is the correct one to use?
