Default Changing Front Brakes

So I've noticed there are a couple threads on this, but for the life of me, I can't figure out what size/type bolt is holding the caliper in place on the inside of the caliper. I've done many a brake job on different vehicles and never run into this issue, but I just can't figure out what it is back there and nothing I've tried seems to fit! Anyone who's done this have any insight? Thanks in advance!

Assuming you've tried hex keys, etc? A photo would be needed otherwise.

I'll see if I can get a quality picture when I get home...I've taken some really terrible quality pictures and it looks like it should be a hex key. problem is that I've tried every hex size I can find that looks close and no luck. Stay tuned for a picture!

Is it a 4 square - i.e. 12 splines?

You probably mean triple square which has 12 splines.

I bought a whole set of those in different sizes and 2 lengths as they are used fairly widely.
