Need a bolt head measurement, please.

[HO455]

Thanks guys. They are a carriage head style with an extra large head.

I found a old box full of what looks to be the same bolt. I didnt have an original to measure to be to confirm they're the same.

I should have posted this picture. The #1 bolt is what I was looking for.

I used a non-factory style replacement when I replaced my floor. I was unable to locate factory style replacements. Well the truth is I could have gotten them if I wanted to buy 5000 of them and wait like 10 weeks for delivery. Now if I could have gotten 999 patient Burban owners to step up I might have gone for it.

Thanks for the offer Doc but I shouldn't need anything more than the measurements.
