Help on stupid bolt size

[_Sheffjs_]

This is so stupid! I have two interstates that are s-valked. What is the stupid freaken size of the two bolts that hold down the front of passenger seat when using a two piece seat set up?? 

I have bins and bins of metric bolts and found bolts that work fine on both bikes however they can't be the right size. They feel so sloppy threading in, but yet they hold fine.   Thanks, Jerry

The previous owner of my bike put a set of Ultimates on it and the bolts were too long and the wrong thread. I ended up re-tapping the threads and put a set of stainless M6 (I think) bolts.
