I assume that are you talking about the Burton bindings. If so then read on
Well, the binding screws that attach the binding to the board would have to be M6x16mm with a phillips head. Part number 90258A285 at mcmaster.com. As for the cant screws I bet they are M6 too but I do not know the length as I don't have them. But if someone has them they can measure the length as shown in the attached photo.
If you are talking about the TD1s then that is something else, and the TD2s would be something else too. So... let me know and I'll see what I know. But I know what both of those are for both the binding to board and cant screws.
