Peachtree screen latches

Hmm..Perhaps you may be able to use the 33-084 screw for the 70-208 screen latch set. If you decide you want to use a pop rivet, you may want to consider the 33-006. You will just need to keep in mind you will have to drill a larger hole in the screen clip. See which idea you think would work best for you.

I'm actually not sure how Peachtree locks these in. If you say the screen can't come apart, though, then we'll need to find some way to work around it. In the past, I've used our 70-009 pull pin (not the cap that comes with it, just the pin). What I had to do was drill a tight hole and installed the pin so that it stays in place. 

Regarding the pop rivet, if you have an older screen you can look at that for a reference. If memory serves, Peachtree used a larger diameter rivet. I think it was 5/32" in diameter. You could consider our pop rivet, or if you needed something bigger you can check a local hardware store. They should have something in the size you need.

The screw should work in an extruded screen.
