G'day all,
I want to fix a light weight ceiling light on to the ceiling (plaster board). Some reason I removed and saw holes everywhere, and the screw used doesn't look professional at all, One of the gyprock screw I couldn't loose it neither tighten it, temporarily fixed now.

I want to fix it back with proper screws even though its very light LED ceiling light. Any suggestions are welcome. And thanks for your time in advance.
Have a good week end.
Regards
Praveen
