...i found them in one of my F100 bolt buckets but i donīt remember where they belong !?

 

They look like body bolts. Could be door hinge, fender or radiator support, front air deflector, etc. They likely would go into a captive nut somewhere.

 

53/67 Door Hinge Bolts?

 

door hinge to body. Not hinge to door.

 

That's what I meant, but I can see now the need for clarification.

 

so you guys mean this is not the right place? :

 

According to my Ford literature, those in your picture near the radiator would be Ford Part 20347-S8 5/16-24 x 3/4. The ones you initially pictured and inquired about seem to be longer than 3/4, but maybe the camera/angle is playing with optics...

For reference, look at this offering: https://midfifty.com/item.php?INV_ID...bolt-set-stock

 

yes thats what i thought also... they seems very long for that radiator support.

 

Grrr! I know these bolts well. Ever tried fitting a door up into its hinge by yourself and trying to reach a bolt that is just out of reach...

 

Since i found 12 Door Hinge Bolts in my Door Bolt Bowl, maybe iīm gonna use the other ones for the Radiator Support.
Thank you guys for your suggestions.

 

I buy those bolts new and use them whenever replacing/installing a door. That said...what is the difference between these "body side bolts" and "door side bolts"? I use these bolts on both sides...
