You mean like a full-size one, for a telegraph cross arm?  I've got a cross-arm with 'spuds' on it that I can measure for you.  It's really shallow threads on a long taper.

I'm not sure what it is either but it looks to be a 1 1/4" tapered Acme thread.

Hello Ed:

I don't know if this might help you:

If you're looking for a pin for your insulator, I can probably help you if you private message me. I will give you fair warning, however, that like many collectibles it is difficult to stop at just ONE insulator!
