What size bolt is this?

[Ty's Si]

Hoping someone can tell me real quickly what size this bolt is. Not the size of the head, but the size of the threads.

Thanks

theres not really much to work off of...

The two bolts that go into the chassis?

I just need to know the size of the threads. That's the clearest image I can find.
