I have a few thread insert gizmos that are like the type you described DoN,

I picked up somewhere.
An obvious resemblence is the different thread pitch of the OD/outer thread
to mate with the item to be repaired (or strengthened).

The metal thread adapter/reducer portion looks a little strange, a kind-of
charcoal color, not at all like shiny cut steel.

O.K. That is about what I have, except much smaller with only
two keys, not four.

There are 4 shiny staking pins (triangular in cross section), and when I
looked at info about these types of products (don't recall which particular
brand), it was recommended to use the manufacturer's driver for driving the
pins.
Many manufacturers have special drivers/arbors/etc for their products, which
may not actually require anything more complicated or special than a pin
with a shoulder or flange feature which could easily be made in a lathe.

I was lucky to acquire the driver with the inserts, and they
have both a pin to hold it concentric while driving with the keys, and a
part which is struck with a light hammer to drive all of the keys at
once.

The name "Kensert" comes from a concatenation of parts of "keyed
insert".

And I got the name from markings on the driver tool.

Enjoy,
DoN.
