Also easy to inspect and repair.
Nut hidden in middle of core relies on core strength, so needs much more core reinforcement.
And if it starts to break, you won’t know, until it fails completely. Also, every time you tighten the bolts, you will risk over tightening and damaging hidden parts.
If the nut is on deck, you can see if it is corroded, cracked, tightened too much and starts to crack the deck, etc. You have a chance to see the problem and fix it fairly easily before snapping the board or losing a foil.
It is not a problem if the insert doesn’t reach the bottom of the board.
Suppose the widest part or "head" of the T nut base is 20mm.when I drill out the columns in the board and fill it with epoxy for the t nuts, should I drill the column wider than the head of the t nut (so the prongs of the t nut grab epoxy when I insert them) or narrower than the head (but wider than the barrel) so the prongs grab wood? I would assume the former, so there is less potential for water entry into the board but I’m not sure.
