What is the recommended drill bit size for the pilot hole?
2
Usually no pilot for these are needed but if driving into the end of the board, like when laying down 5/4 and butting board ends, i can see where it might split, id go no bigger than 1/8 inch diameter, but only the decking, not the joists
