Undercover bolt

[BeigeCorolla]

Hey guys Happy Holidays,

I was working underneath my car on the passenger side engine bay area. I was in the process of the taking the undercover/splash shield/plastic undercarriage cover. Common sense dictates that before loosening bolts that are consistently subject to harsh road conditions, apply a little WD-40. However, common sense was on vacation today, and low behold removing one of the bolts, it snaps, slightly cracks the shield, and leaves a small piece of bolt in the frame. Question I have, is im probably gonna have to buy a bolt remover of sorts, and was wondering what size that bolt is. To specify which bolt, its the one that located the closest to the bumper and passenger side headlight.


Thanks

If it is one of the ones I have in mind, it is a M6x1, and takes a 10mm socket
