What size drill bit should be used to make the holes for the screws?
1
If you are mounting into wood studs, a common screw size is #8 or #10 wood screws. For #8 screws, use a 1/8" drill bit for pilot holes. For #10 screws, use a 9/64" drill bit for pilot holes. If mounting into drywall or masonry, use appropriate anchors and follow the anchor manufacturer’s drill bit recommendations.
