There are 3 very small (3mm - 4mm) bolts that stick through the front bumper cover that the fog light buckets mount to with tiny little nuts. Does anyone happen to know off hand what this thread is? There are 3 per side (driver's side, passenger side). I plan on using these to mount my fog light ducts and can't figure out the thread of these and don't want to take the bumper cover off to find out.

Thanks!

 

I believe they are metric threads - funny you should ask - just added 3 nuts that fit from my box of nuts and bolts last night - they were from my metrix bin

 

i know they are metric, but i need to know what size coupler nuts i need to buy that fits them.

 

Can't vouch for the thread pitch but PET shows the nut as M5 (5mm).

 

so the three bolts on each side that stick through the bumper cover are M5? Sounds about right to me, thanks!

 

Here's a screen dump of all the parts in that area in case it helps. I guess you were talking about part #6.

 

not sure if that's it or not. but i almost got a 3/16" nut on there, so M5 is my best guess so far.
