Bolt size intake plenum ground wire

[300kmi97camry]

Can anyone please tell me the size of the bolt of the ground wire on the fire wall side of the intake plenum. The wire next to the passenger side plenum brace/bracket. I was replacing the rear vavle cover gasket-not a task I ever want to do again and I dropped the bolt and can't retrieve it. I know it has a 10mm head but how long is it? It's a v6 1997 camry LE
Thanks

Dont worry about the head size. Only thing that matters is the thread size and length. It will be metric ie 10x1.25. Go to a parts store and get different sizes and lengths and with trial and error you will find the one that works. You can take back the ones that dont work.

I have a 1997 Lexus ES300 V6 (part for part identical except for engine cover) and the bolt is 12 diameter x 8mm height. bigdaddymak20's advice is correct regarding thread, but that is the height if it helps.

Thanks guys, I'll try to get to the parts store today and get some bolts. In the mean time I have the ground wire pinched between the plenum bracket and plenum. The car runs fine but now my AT pan is leaking. Will prolly try to do that next weekend.
