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.
