You know I found my allen wrench set and none of the wrenches fit

The 2.5 is too big and the 2 is too small. Maybe the are the wrong type of wrench?

I do have a Star Bit T-27 that feels like it fits but not sure if too many ridges on that bit. I don't want to strip it out

Maybe it is SAE sizes??

Yes, it is just for decoration but it isn't tight, I just want to tighten it down.
