Re: Best way to add bolt threads in the board for the mast when building board?

Tee nut on top is stronger. Keeps full board in compression and spreads loads to deck and bottom.
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.
