What size nut goes onto a typical US passenger tire Schrader valve?
To insert the tire valve, I know there is a ridiculously cheap cross-type valve tool where you thread it on the outside of the tire valve to pull the tire valve through the hole in the wheel rim, but for emergency use I just want to stock a few nuts that I can thread on the outside of a new valve to use as a ledge to pull the tire valve through the hole as shown here:
Assuming "Imperial" means "USA", that would mean I need a 32 TPI nut somewhere between 0.271 inches and 0.305 inches in iD, but that doesn't seem to be a standard size for a USA nut.
