I personally like the 70-009 pins. However, it would depend on exactly you plan to use them for. Pella normally uses a knife latch (like our 70-143P) for their screens, not plunger pins. If you are making new screens, a pull pin could be a good alternative fastener. The knife latches are a little difficult to install in a new screen. I have used pull pins in the past to install a screen in an Andersen window in my son's apartment and it worked very well. All it took was to drill some holes in the screen frame and into the window frame to secure the screen.
