Belly panel Wheel housing cover bolts PN 07149126886 or 07147129160

I have trying to find the correct bolts for my e92 M3 and e92 335i belly pan and wheel arch covers. From realoem,

https://www.realoem.com/bmw/enUS/sho...diagId=51_5860

07147129160 seems to be the correct PN. However, these bolt's washers are smaller than the ones on my cars. They don't look correct to me. The one that looks very closed is 07149126886 but it is not shown as M3 belly pan parts on realoem. On ecstuning, 07149126886 appears to be the same bolt on my M3 and 335i.

Any idea on the correct PN?

BMW installed two types of these trim screws in these cars depending on what they're attaching and when it was built. Your LCI cars would have come with the coarse thread 886 to secure items like the undertray parts. You can often confirm what's required by whether the "threaded" nut plate is dyed green- those require the coarse thread screws with the wide washer.

Throughout the car you'll still find the 160 fine thread screws used. You need to keep both types on hand as you'll need both from time to time.

Thank you very much. Finally, screw type mystery got solved. I am going to order some 886 for my LCI e92. I will take a look at nut plate dyed green color. How did you figure out these two screw types?
