Gentlemen, what is the preferred fastener for the Morris deck pieces? I have 3/4 escutcheon pins for the top and side caps as well as the center trim piece. I did not disassemble this project and I have no idea what was used to attach the decks. The original pieces cleaned up pretty well but I need to treat them with some TLC. The fastener obviously need to sit flush as they are covered by the cap trim. Thank you
