Screwing into dual pane window frame?

[2Driver]

I want to put a solar screen over a west facing fixed window and need to screw in casement turn clips like below.

Anyone know what the rule of thumb is for being sure I will miss the glass when screwing these into the frame?

It those are double pane windows, I'd be concerned they may be filled with Argon Gas and you will ruin the windows. I'd look for a safer approach and maybe drill into the brick below the window and somewhere up above the window, possible into some wood portion.

My concern too.
The glass module is in the frame only so far, so I’m thinking I can screw into a place on the frame that would be outside of the glass module. I’m just not sure how far into the frame the glass goes.

I wouldnt screw into window frame.

make some little 1x1 angle pieces out of aluminum paint em to match and attach to the sides then screw to those. Basically making a stand off/ spacer

If you have no other option I would drill a small pilot hole to check for depth and clearance then drill/tap the hole and use a fastener short enough to engage 1-2 threads through the frame.

Talking with my old man, he measures 1/4 below the frame, not the rubber felt. I’d say anywhere below 3/8 should be safe if this is your only option.
Otherwise like others stated, do a stand-off or run some angle iron into the brick and screw into those.

I might try 3m dual lock and see if that works.

I don't have the answer, but my local glass shop drilled and screwed into the corners of our windows, they cracked six out of seven windows. Be careful.

Works great...
