Exclamation Screw Size.

So if I had managed to lose all the 4 screw to the front plastic grille. What size would they be to buy new ones.

So always best to tell us what year when asking questions like this.
In my '00 parts catalog it is listed as a SCREW, Pan Head, #6 HiLo.
Please don't ask me what that means cause I don't know.
The part number is 6034204.
Sometimes they list the specs. This time they don't but.
What they did do is list the specs for the plastic piece it screws into.
NUT, Plastic Snap-In, For .164-15 Screw.
No idea what a .164-15 screw is.
Almost thinking it doesn't really matter as long as it screws in the somewhat comfortably.
Just so you can see what I am looking at.

These are panhead hilo screws. The threads alternate from high to low.

Look at that. LOL.
What is the logic behind the threads alternating like that?

  • Perfect screw for low-stress applications
  • Reduced cracking in plastic bosses
  • Smaller sized bosses can be designed to save in material and space
  • Increased pull-out resistance

Mostly reduced installation torque and less likely to strip or crack the plastic. They're also harder to reinstall if you take them out and try to start the screw in 180* out from the original. Most of mine got replaced with plain old stainless pan heads and new plastic inserts from the Help! section at the auto store a long time ago.
