I have a friend who is looking to use some head bolts for another project, (some miniature bridge thing) When I was swapping out my bolts for my studs, he commented that they looked almost the right size, but we never measured them. Unfortunately when I was done my stud install i tossed them out. So if anyone has a set or even just one kicking around and can grab me a couple measurements, it would be greatly appreciated.

-Length of shaft (so just under the head to the tip)
-Overall length
-Thread Pitch (I know they are 12mm X ???)

Thanks.
