NOFMA installation specifications state:
Lay the first strip along the starting string line, tongue out, and drive 6d or 8d flooring nails or casing nails (galvanized or screw shank hold best) 1" from the grooved edge. Nails should be driven into the top surface of
strips and counter sunk (face nailing). Position nails over supporting joists, and near ends of strips or into each screed crossed. Keep the starter strip aligned with the string line. (Pre-drilling nail holes will prevent splits.)
Also, blind nail starting strip through the tongue according to nailing schedule.
