Factory rails or steps bolt size.
I don't recall the size, but it was sort of an odd size the the auto stores and big box stores didn't carry.
I found mine a local ACE hardware that truly has the best hardware selection around. Best bet would be to take the bolt in with you and see if they have a thread gauge and can help you match it.
If you don't have a good hardware store around and your in a pinch PM and i'll try to stop by mine to match it again - they have crappy hours though so I'm not sure if i'll be able to get there before the weekend.
