So how exactly do these work? i.e. the transferring of the threads from
one hole to another? I am having a hard time picturing the application.
Thanks

Thanks, that was perfectly clear. They are sort of the machinist's
equivalent of dowel centers and serve as precision center-punch marks.
Cool, I finally achieved my required learn one new thing today. :-)

This sounds like a good possibility, though it doesn't explain why
both ends have points.

You might be onto something with this idea, I'll look into it.

That was my thought, because it seems to have much in common with a dowel
centering point.

I don't think so, because it has a point on each end. It looks
like it's susposed to thread into something, and that thing is
susposed to be able to rotate (with the two points being the
bearings).
You're right about why the slot is off center.

I would guess it's for transferring the location of a threaded hole to
another piece of metal. the slot is for a screwdriver, off centered
because that is the critical part of the piece.

who has made really dumb guesses before, and sees no reason to stop.
Let me confirm it's for transferring threaded holes from one metal piece
to another. I'm a tool and die maker and have used these at work,
although they are of an older style. The newer ones don't have a
screwdriver slot, they have a hex shank machined on one end opposite of
the point. You use the container they come in to screw it into the
tapped hole. The tube shaped container has a mating hex shaped cavity
which acts as a driver.
