These hooks work with boards that have the screws that go through the base of the board. This is currently the most common type of hook mounting style. If you have screw heads showing on the base of your board, you need through style Hercules Hooks. If your bases are smooth, with no screws coming through, you need Insert Hooks.
One package is enough hardware for one splitboard.
