I never had any problems with the original 13 mm hex bolt on the Nuovo Super Record seatpost. Always used the Campagnolo #2025 "Special brake spanner" for adjustments (wrench measures approx. 6" and thin). Also never had the adjustment slip, so I never carried the wrench either. (I also never had problems with the Cinelli 1R stem though, so my experiences might not be the norm.)
