Need a bolt head measurement, please.

[HO455]

If someone has some time to measure one, I'm looking for the diameter of the head of one of the factory wood floor bolts. It is one of the 5 carriage head bolts circled in the photo.
The 2nd photo is one I removed when I replaced my floor. I didn't keep it unfortunately.
Thanks in advance.

I should have a decent used one. I will check in the morning. They have a special name but for the life of me I can't think what it is.....

Are those called Elevator bolts?

I believe so.

I’m not sure how accurate my measurement is because I’m checking it in the truck but I got about 13/16. With it being recessed I can’t really get a good reading but the hole is measuring just over 7/8.

I had to regroup and delete my first post. I didn't read your text close enough and just looked at the picture. I thought the picture you posted was a flat head bolt but I see you said it was a carriage head bolt.

The original carriage head style bolt I have measures 7/8" head dia. x 1 1/8th inch long, (measured from under the head) 3/8 bolt size. The head is flatter than the carriage bolts of today and is perfectly smooth.

I can send you the one I have if that will help....

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.
