Pegs go all the way through. They're not fake. Raising crew sawed then off flush on girt side. I'll check to make sure they're snug, however. I would imagine they're REALLY snug now. Thanks for input. Stair stringers are pocket screwed into the girt -- perhaps I should unscrew them and let strings float on top, though I can't imagine they'd move the girt/post much either way.
