What size/pitch is the idler pulley bolt

[eds72]

It looks like someone who put this in before killed the threads at the end of the bolt. I think it's a M10 but can't tell what thread pitch. It looks like either a defect or someone partially shaved off some of the thread.

My searches haven't turned up the answer yet.

V8 or V6, but most likely doesn't matter because if I'm not mistaken the V6 is similar if not the same as the V8 and is a left handed/reversed thread and you will most likely not find a replacement anywhere other than a savage yard or your local Toyota dealer.

If I'm incorrect and it's a right handed thread take to to your local Home Depot/Lowes or hardware store and they should have a pitch/thread display that you can match it up to to find what pitch/thread it is.
