plunger pin for Marvin screen

A home owner from Erie County, PA says:
I am looking for replacement plunger pins for the screens that came with our Marvin double hung windows. Can you direct me to the correct part? I'm thinking it may be 70-008.

I'm not sure what plunger pin Marvin uses in their screens. Compare one of the original pins to the dimensions we offer online for this product, let us know if you need any more measurements in order to make a decision. If they do not seem to be a good match for a replacement, please reply with a photo of your pin for us to research.
A home owner from Erie County, PA says:
Since this isn't exactly like any of the ones I see online, I'm not sure where to measure.
Thank you so much.

Please take a look at the 70-008 and 70-009. Remove one of the pins from your screen and see if the dimensions are a match.

Do you have 2" plunger pins in a dark finish?

Both the 70-008 and 70-009 are metal pins with black caps. We currently do not offer these pins in another finish.

I'm doing this same replacement of plungers today. At least I thought I was... Can't believe Marvin Integrity(?!) put clear plastic plungers instead of metal on their screens. It's now 10-years later and they are yellow and crumbling - and I'm wasting my day trying to fix this!

Marvin has an oddball size: 0.155" (5/32") head that is 3/8" long and a 0.118" (1/8") shaft. I just picked up some 7/32" heads, 0.125" shafts locally (the only size stocked) and while they didn't fit the screen frame hole, but did fit the window frame slot. So I drilled-out the screen frame to 1/4". Plunger and shaft fit. Went to install in the window and it won't "click" into the exterior frame channel. And I can't get enough of a grip on the screen to try and wiggle it in.

So there is enough difference between a 5/32 and 7/32 diameter to make it fit or not fit. The 70-009 part is the one with 5/32" plunger head.
