Oil Pan Cover/Guard bolt sizes?

I did an oil change recently and noticed that there were a few missing bolts for the oil pan cover/guard. Does anyone know what size bolts I can buy to replace them? Attached a picture below of what I’m talking about. This is for a S2 btw!

Do you want sizes or part numbers? My S2 came to me with one having been swapped out for a different size by some shop monkey, and I'm super **** so I ordered new one(s). I might have one still in the Mazda bag in a drawer. I can put a thread gauge and caliper up to it if that's what you need.

Part number would be great. I was having a tough time finding it on Mazda part sites. Not sure what the exact name of this under tray is. If you don't have the part number, size would be good too. Thanks!

I believe you'll find these are what's used for all fasteners holding up that tray:



As for the oil drain plug, I use this site for the parts diagrams to find part numbers, then google the part numbers to find the best prices. Oil drain plugs are pretty generic though. Dorman type parts you can get at your favorite FLAPS.

This is perfect, thank you. What did you torque your bolts to? I replaced my drain bolt with a Fumoto valve, so no worries there.
