Bolt size for "IS" Spoiler?

[KenC]

I have the little "is" trunk-lid spoiler, and I need to know what size bolts go onto the threaded posts coming out of the bottom.
Thanks

10mm plastic nuts, same as used to hold on the fender liners.

I was planning on going to Home Depot and getting some stainless washers and nuts to mount it. Does anybody know the thread diameter of the nuts I should get?

Looks like M5 for the nuts

just bring the spoiler with you to the store and match em up there. thats the easiest way.

Ken the size you need is "M5-.8" I went to home depot and couldn't find them anywhere. I had to go to a special bolt store to find a pack. Good luck.

Just for reference, the more common metric sizes are: M4x0.75, M5x0.8, M6x1.0, M8x1.25, M10x1.5. After M10 my memory gets sketchy but I think the thread pitch starts covering 2 different stud sizes; i.e. M10 & M12 are 1.5, M14 & M16 are 2.0, etc. The first number is the diameter of the bolt/screw in miilimeters and the thread pitch (2nd number) is simply the measurement in millimeters from the peak of one thread to the peak of an adjacent thread. I hope this helps you out...
