I just purchased a 2010 Skate Banana 159 Wide and was wondering what size hardware is to be used with my bindings 12mm? 14mm? 16mm? 18mm?. Last year I had a skate banana and couldn’t find the right size (either too small or too long) and it messed up the base of the board.

Hardware length varies with each brand and can vary with each model of binding. You want a minimum of three full screw turns engaging the board threads.
