Skid plate bolt size - 2018 Hatchback EX

[tchubaba]

So I noticed the other day that my skid plate started scraping against the ground while I pulled up in my driveway. Took a peek underneath the car and noticed that both front bolts that hold the plate in place were gone.

The plate looks exactly like the one from this post https://www.civicx.com/threads/skid-plate-problems-2017-ex-t.28645/. And the bolt maybe something that looks like this:

Now, I have no idea what size that is, nor do I know the part number.

According to this post https://www.civicx.com/threads/skid-plate-hanging-sport-hatch-question.29977/#post-502358, this should be the bolt I'm looking for:

But according to the site's "check fit" function, this will not fit my 2018 Hatchback EX. I couldn't find one that would.

I'd be very thankful if anyone could point me in the right direction here on figuring out what size this is or if there's a part number so I can order replacements.

Much appreciated.

Did you car see the dealer for a oil change ? Or under work ?
If yes it is well discuss here, the mechanic forget a bolt or tightened them, return car to the dealer

Wrong bolt

Those are the 1/4 turn.
The others should be the same as above.

The bolt show on the OP picture are not the 1/4 turn bolts/ screw , they are regular threaded bolt

I take apart a bolt from my car . It is metric size ; M6-1.0, 1.5 cm long

I did see the dealer for the first oil change, since it was free, but that was about 6 months ago. Seems unlikely to me that they were gone all this time... I'm guessing the mechanic didn't tighten them very well and they came off now.

Thanks mate, but like other said this is the 1/4 bolts. They go on the sides and back of the plate. There are 2 bolts on the front of the plate that are regular bolts, and these are the ones missing.

Sure it is, I do my own oil change. Never loose any bolts / screw
By the way , nothing is free, you'll learn.

I return to se the dealer

That was right on the money. Bought two M6-1.0 from the auto parts store and installed them, they fit like a glove. I had to get a washer to hold it in place though, because the replacements head weren't wide enough. But it's all good now. Much appreciated latole!
