Replacement plunger pin for window screen

I need to replace a missing plunger pin on a screen. The screens were installed with Marvin windows in 1997, no other identifying information. I am sending photos of the existing pin on same screen w/ a measuring tape to show size. (FYI - the tape measure is laid across the top of the screen frame, so there a very slight curve in it, which could distort the measurement a bit.) I believe your product # 70-009 is the closest match, and it even looks like better quality. (This one is plastic & the heads become brittle & break off.) Do you agree? Is this what you would advise I purchase?

Much appreciation,
Kay
