On normal electrical boxes, screws are usually 6-32. this being a bit light for a fan, also expect 8-32 or 10-32. Ground screws are 10-32. It's not a coincidence that they are -32, given the thickness of standard metal junction boxes, that is the minimum number of threads to properly engage. Never use sheetmetal screws.
