Nah.

Yes, there were some brands that used square drive recess seats.

But I would say the majority today do use hex drive.
OP said he had an allen wrench in there....

The stepped tools are built that way so that the tech only has
to carry one tool to service a range of seats.

The tapered tool is made so that it can be "driven" with force
into a seat recess that has been damaged. It's the tool
of last resort...
