CherryMax Rivets for exterior which one to buy?

[RSchmert]

I have read the previous posts for exterior rivets and it seems like CherryMax is the rivet of choice when you can’t do a buck rivet (over Olympic). I am trying to order some but am struggling finding the right rivet. It sounds like 5/32 (unsure length) but does anyone have a part number or supplier that they like? A basic google search gives me a ton of different part numbers. Thank you.

Was it @Salty that used these?
