I am trying to figure out the specs of this bolt. If anyone can tell me by looking at the attached picture I would appreciate it.

Looks like it was intended to rapidly secure or adjust something. It is not going to be very hard or strong. That’s about all I can tell from the picture. Similar to this, but smaller: http://www.ebay.com/itm/NEW-SNOWMOBILE-TRAILER-TIE-DOWN-BOLT-CRANK-HANDLE-1-2-THREAD-1-2-INCH-/371479567584

That’s an RT-LL, possibly 5/16″.
