Note from the manufacturer:

It is essential to use a medium-strength threadlocker on the thread (e.g. Loctite 243).
If you only change to an oval road chainring on the inside and keep using a round chainring on the outside, continue to use the original bolts.
With the round CX chainrings, the nuts may have to be filed down to fit properly (depending on the crank).
