Brass bolt, civil war?

[collector01]

Found this today at a civil war camp. Any ideas of what it is? Thanks

Hmm, apparently has left handed (reversed) threads. Maybe part of a worm gear set-up?

That's not a normal bolt thread. I would also go with worm gear for a leveling device.

Agreed. Leveling screw.

It does look like an Acme thread and it could be a leveling screw like others have said, I found this leveling screw from a cannon online.

Elevating screw for a field gun.

Could be the same one. : )

You can see where two of the wings broke off in Collecto01's photo?

It also could be out of a large gate valve, any irrigation going on nearby ?
