That’s where the retaining push pin type button for the inside firewall insulation protrudes.

I have 2 firewalls here, the heat only has the hole on the protrusion.

The ac/heat does not have the hole.

And what bodyperson said

They must have made them that sharp for a reason. Maybe to pierce the insulation without needing a pre formed hole. Ya, ouch!!!
