Fastener specs for Kia K5 undercarriage covers

[Autumn Fresh Fleas]

I got a 2021 K5 as a company car, and the undercarriage covers are off and banging around. I don't have the original fasteners. Is anybody familiar with the right bolt sizes for reinstalling those?

You can try using M6x20mm bolts and plastic clips to secure the undercarriage covers on your 2021 K5.

Appreciate it, man. Did you use U-nut clips with those or go straight into the body? I saw a few listings that mention both types for splash shields.
