Bolt size for Bumper cover to Fender 2006 Malibu Maxx 3.5L Sign In

I have to remove the bumper cover on the above car. The 4 bolts on the right and left ( 2 each side) that hold the cover to the fender are some unknown size. 10mm is slightly too small and 11mm is way too large, it's like the bolt is 10.5 mm 😃. I tried SAE sockets / wrenches. I wish I still had my Whitworth tools from when I had Triumph motorcycles😆. I looked online at a Chevrolet dealers parts exploded view and you know what? it does not show those bolts. so if anyone knows let me know. I have a radiator to replace before it gets way too cold outside.....thanks
oh yeah i have the factory service manual from Helm and they mention nothing except remove the bolts.

They should be 10mm if they don't have a torx center

I know HT that's what everyone says. Tons of videos of ppl removing the bumper cover. They had a light coating of paint. i have had bolts that were painted that a socket would go on. i took a file and tried to remove the paint on 3 sides. just a light coating, like i said should still go on. and no Torx center

Well, if somebody changed the bolts I don't know what to tell you but I have never run into what you are describing. Retainers are pretty standard.

Oh my! Are they Martian and 5 point or something + you didn't notice.

IDK, can just Vice Grips or "extractors" get them out, match threads needed and put back something less brain dead,
