Was concerned that even expanded the clips might not be a tight fit.
Managed to size the hole in the metal cross member using the shank of a drill bit.
Rejected some clips offered by a Honda Dealer (his IT was down so could not get part number!)
From memory think the unexpanded diameter was 12mm - best do your own checking!!

The 2 rear ones are 10mm and I think the fronts are too.

Here's a photo of the genuine Honda rear undercover fixings , 10mm wide , 10/12 mm long

you dont touch the front plastic clips to take the undertray off

there are 3 metal screws each side and a plastic 10mm on each side at the back
