What size nut goes onto a typical US passenger tire Schrader valve?
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 he https://d3vl3jxeh4ou3u.cloudfront.ne...e%20pliers.jpg Looking for what nuts to purchase, the Wikipedia for Schrader valves says the typical passenger brass & rubber tubeless tire pop-in Schrader valve has OD threads of: *TR 418, 0.453 in (11.5 mm) rim hole diam. 2 in (51 mm) long*[*] Metric: 7.7 mm OD, thread root diameter is 6.9 mm ? 0.794 mm pitch[*] Imperial: 0.305 in OD, thread root diameter 0.271 in ? 32 tpi (threads per inch; thread density) 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. http://www.engineeringtoolbox.com/in...nts-d_471.html Even if I look deeper into the granularity, it still seems an odd size: http://www.liming.org/InMoov/pics/decimalchart.jpg So I simply ask you if you have experence with this problem.

You need a cap anyway, so it's always there in an emergency. |

Can't you just use a stem puller tool; instead of the core tool or a nut. Much easier. <https://www.amazon.com/Milton-S-449-Valve-Insertion-Tool/dp/B000K1PKFY/ref=sr_1_3/151-3094190-8516300?s=automotive&ie=UTF8&qid=1481049631&sr=1-3&keywords=valve+stem+puller#productDetails> or <https://tinyurl.com/hve25mc> Sorry about not answering the thread size. |

You may have a TPMS stem. If you insist, I would get some extended metal valve caps and have at them as you wish. Remember the valve cap has a very large job of keeping the air in the tire as schrader valves are dodgy. -- Tekkie |

It amazes me why some people want to reinvent some things. https://www.google.com/search?q=Slim...alve+Tool&rlz= 1C1GGGE_enUS434US449&oq=Slime+20088+4-Way+Valve+Tool&aqs=chrome..69i57 &sourceid=chrome&ie=UTF-8 -- RonNNN |

Get yourself some brass stock, take ten minutes to cut one on a good lathe. >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. Sure isn't, that's deliberate. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

The actual thread is a ..305X32 - which is NOT a standard fastener thread. |
