Is this a wheel weight?

I found this recently and am curious if it is a tractor wheel weight or something used on a drilling rig? Any thoughts?

My thought is not a wheel weight.

It looks a lot like a drive bushing for a drill rig table. The inside hex would turn the kelly bar which would spin the drill stem. However I cannot be 100 percent sure.

With a little imagination, it could be a wheel weight.

Not a wheel weight. Wheel weights are generally "as-cast" designs, with zero or minimal machining work. This part has a lot of expensive and unnecessary machining ops on it, no way would someone put that sort of time and money into a wheel weight design.

Looks like something designed to engage and spin another part, given the hex broach with intersecting pin socket on ID and two machined splines on OD, with corresponding attachment holes. The guess at drilling rig hardware seems reasonable.

That said, if you could find a matched pair, I've seen people use things much worse than that, as wheel weights.

I think it's the wedge colar for securing a wheel to a straight axle

That's what I was thinking. Kelly bars have been outdated for a while.
