Nate what are ya doing for a backing plate or are ya using washers? Countersink holes for washer so the nut remains flat is kind what I'm thinkin? Or make a thicker threaded backing plate and using round holes instead of square ones... thoughts?

A guy has a couple options. I figure most folks have a spade bit in the least, and some forstners if they're fancy like me. :msp_biggrin: LOL
Drill the holes backwards. . . Meaning, pick your washer size. Lets say they're 1" dia. -- so start your holes (on the back side of the board) with a 1.25" (1 1/4") bit as deep as you want the countersink.
Then switch to your 'through' bit for finishing the bolt holes. 1 size over for 3/8" bolts, or 1 size over for 1/4" bolts, whichever you chose for your shoe. Doing it this way means you have to take a little more care in your layout (everything is backwards), but the counterbored holes give you guides (the center point) to finish drilling the holes all the way through the board.
Anyone who has tried to do a flat-bottom counterbore after they've drilled their holes can attest to how much it sucks doing it that way, as opposed to the way annotated above.
Hope that's not too confusing? :msp_scared:
