These are on my mama bear. The stove number is PA84. I've never seen this type of bolt or screw on any other draft caps.

Someone replaced the originals.
They were 1/2 -13 hex head bolts, 3 inches long with threads to the head with no head markings. Bolts with head markings are hardened.
For collector purposes, originals are best and hard to find. You can make them from any bolt by grinding, filing and sanding the marks off the head.
The nut under the cap was a "half nut", but a full nut works and was used if they ran out. Some fabricators used full nuts.

New old stock air damper bolts.

Thanks for the replies. I had a feeling they weren't original. They're all cleaned up now and work great, so I'm leaving them alone.
