Door Hinge Bolts

Hey all,
Does anyone know what size bolt that are in the door hinges of a 69? Are they 5/16-18 x 1 inch with a flanged washer? Do the threads go all the way from flange washer to end?

Thanks

I think you have the 5/16-18 but I think they are 1 1/2 inch with a shoulder.

They are 5/16-18 x 1.125 long.

Yep, that looks like the one.

Perfect. Thanks all. I was curious if they had threads all the way to the end or if there was a lead end on it. Your picture explains it all thanks Trixie.
