Screen corner dilemma

Hello Swisco


I'm having a bear of a time finding internal corners to fit my screen frame.
Most recently I tried Swisco 95-013M, the ½" x 3/16".

They don't fit into the frame of the aluminum screen that I have. I have already tried the 95-012M and those were way too big.

So my question is ? do you think the 95-113 is the ticket? I feel like that's the only option remaining for me, but I am curious to hear your expert opinion. Admittedly, I haven't taken a sledgehammer and tried to pound the 95-013M's in, since that seems an inelegant option.

Here are some snaps of the corner I currently have (the white one) against the 95-013M. Please let me know what you think?
