✅ SOLVED Threaded fitting?

[Blackfoot58]

Non-ferrous, silverish-gray. Pipe threads (I believe) on the male portion. The hex cap has no threads in it. I’ve seen similar that had a jam nut to hold them in place. Initially I thought possibly a fitting to hold an indicator light with a snap in red lens, but the hex seems to shallow for a bulb.

Casey13 posted to the Today’s Finds forum that he believes it is a model T valve stem retaining nut. I had it included in a photo with more items.

I’ve found a lot of these screw in types lately especially at these early 1900 homes sites around the foundation .

Off a tractor hydraulic fluid tank. At least my 1972 ford has one. The small hole sits a breather plug. So one can turn the large one out to do a fill.
