At first I thought it was a ram rod attachment, but those that I have seen have an external thread.

What is the diameter of the largest dimension?

Largest dimenesion is 3/4" and it has internal threds on the small shaft, But it spins inside, and its made of copper, Thanks Diggin, Mickfin

Mickfin,
I'm a Locksmith, and I believe what you have there is a type of locking nut. gas and cable companies use similar type devices. a "key" or tool enters the hole at the bottom and "locks" the inside threaded insert to the outer "knob" so it can be put on or taken off of whatever they don't want tampered with. Then when they remove that key, it releases the outer Knob from the inner threads, so nobody can unscrew it without that tool, it would just spin freely.
