There are no markings on the bay window which was installed 1995. It's not an Anderson. There are 4 of these clips on each window. All but this one are broken. They are not held in my screws as you can see. I haven't tried to pop one out; maybe that's how they are held in?

This white turn clip looks like our 70-014. They are held in with pop rivets like our 33-005. You would need to drill out the old rivet and install the new clip with a new rivet.

Could I drill out or remove the old rivet and install the new clip with a short screw instead of a rivet?

Yes, but you will need to drill a larger hole in the screen clip to accept the screw.
