All wakeboard binding screws share the same universal 1/4" thread but not all screws share the same length.  When mounting a binding without the factory screws, be sure that the screw is shorter than the thickness of the board and use a rubber washer to protect your binding plate.  Although we do not suggest mounting your wakeboard bindings without the factory screws, it can be done.  Using a screw that is too long could result in punching a hole through the bottom of your board or leaving excess screw material on top of the board.  Both options are not recommended.
