I've never bothered with the screws but surprised they are not a good fit. Maybe Tekin never thought anyone would ever try using them
To spend the big $$, but said to be the best, Kyosho zeal tape.
Or the clear 3m tape.
I use shoegoo, it will not come off till you want it to and it leaves no residue. I've ran my RX8 in multiple chassis for well over a year with shoegoo and have not had an issue.
