Do any of you know what thread the license plate screws are...metric, inch?

With the pending CA license plate renewals, I don't want the plates or sticker going anywhere...I'm considering installing a tamper resistent screw.

TIA

 

6mmx1.0

 

Just a related comment - I replaced the nylon license plate screws on my 93LS with stainless steel. The nylon ones cracked when I tried to remove them. Dealer told me this was very common. - Herm

 

What are the screws that hold the air-box to right-above the passenger wheel well?

 

I used SPANNER HEAD screws the size was 1/4 - 20s......................................................................................https://www.clublexus.com/gallery/sh...t=1&thecat=998

 

they are 6mm x 1.0 also.....probably 1.5 -2.0 inches long...

 

Thanks guys!

For now I drilled out the stock screw head and tapped a 6-32 stainless spanner head in there. It covers up the Phillips head for now.
