Factory plastic belly pan bolts

[Emcd]

while changing my oil, I noticed that I'm missing a number of the perimeter bolts are missing. What are the sizes and specs on these?

Pretty sure they are M8 x 1.25 thread. Not sure about the length.

They are 8mm, pitch is 1.25mm. Length is 25 mm. Bolts come with a 25 mm OD washer which is captive on the bolt. Bolt has a tapered end with a cut across the thread to apparently clean crap from the captive nuts in the frame when the bolt is installed. A good replacement is metric flange bolts (local hw store) with 5/16" fender washers.

Never-Seez is good stuff to use on the bolts.

hankinid,
Excellent description of the bolts!!
But, I'm still pretty sure the pitch is 1.25. Standard metric pitches for M8 are 1.25 or 1.0 and I've replaced them standard bolts.
Don't want to send him on a wild goose chase....

badlander, thanks for the correction...shoulda' had the glasses on when I read the pitch gage. Mea culpa, etc...

My original post is corrected.
