Spring-Loaded Plunger Pin Screen Retainer

Do you have a video or diagram for replacing these? thanks

Do you sell the white piece of metal where the pin is attached? if not how is the old pin removed and the new one attached? do you need a special tool to do this? See picture. Thanks so much!

I believe this is the exact part we are looking for. My question: is there a special tool to press these on with or can you advise on how to attach to the screen as the small flange needs to be crimped on?

The attached are pics of hardware for window screens. These are spring loaded and the screen secures to the flange of the window when released

This is a screw in plunger for some larger screens. there is also a pivot pin on the opposite side of the screen.
