question about fastening tops to decks?

[GodsReel]

Anyone ever heard of tapping the deck and using machine screws to fasten a t-top to deck, the guy who built my top and tower claims he has found this is better than wood screws. my deck was recently recored with nidacore and marine plywood (where console and tops would mount) I know that thru bolted would be ideal and i am looking into that. He tapped through the fiberglass and wood or nidacore and used either 1" or 1 1/4" stainless machine screws. I
need your thoughts.
