This is the same hardware used to secure the AMPS balls to our line of RubiGrid® bases. The drilling of 4 small holes is required. For applications where the mounting surface cannot be removed or you'd prefer not to remove it, we provide well nuts or self-tapping screws. Both options offer the convenience of not having to remove a dash panel while still providing a secure installation. Prefer to use your own hardware? No problem. The mounting holes on the AMPS bases are 6mm in diameter so we'd recommend hardware with a diameter of 5.5mm.
