1952-59 Ford Online Hardware

hi guys I am looking for a reliable online source for hardware. I recently removed the doors off my car and I can’t seem to find the 5/16"-24 Locking Flange Bolts for the door hinges. Mine are worn out. Can anyone recommend one? Thanks in advance

 

I bought mine online 5 or 6 years ago..can't remember their name. I did look online for a familiar name with no luck, but I did fiind this company that has them..ss or zinc grade 5, each or bulk.

This link will bring you directly to their ss bolts.........search their site for serrated flanged hex bolts and it'll show you the plated steel ones as well.
I've never dealt with them.
while you're ordering keep in mind they are used on the front fenders as well....at least on my '57

 

Same thing ? https://www.ebay.com/i/202669305474?chn=ps
