Hot take: I ran 12 penny nails in cabinet backs for 9 years until a finish guy in Boise made me stop
I always figured fasteners were just fasteners and nobody would ever see the back panel of a cabinet anyway. Then a finish carpenter named Dale watched me shoot 12 penny nails into a maple back at a job in Boise and asked me one question: what happens when that cabinet sits near a heat vent for two winters. I blew him off at first. Six months later the customer called me back with a hairline crack running down the side panel, and I had to eat the repair out of my own pocket. Turns out the back acts like a brace on a lot of box cabinets, so the right move is usually glue and a few screws, or brads with glue, not a nail gun set to kill. Now I slow down and think about movement instead of just holding pieces together. Anyone else get corrected on something basic way later than they want to admit?
