    shrader Thread tool

    Hi everyone I'm searching for thread tool for shrader valve (inner thread). I'm not familliar with this sort of things. I just know some dimensions like those from wikipedia:
    Internal thread (to accept the threaded valve core)
    Metric: 5.30 mm OD × 0.706 mm pitch
    Imperial: 0.209 in OD × 36 tpi.
    But I'm from poland so it's hard to find threading tool not metric standards.
    So if you know that kind of tool send me link to it so i maybe know what to search for

    Are you just chasing the threads, or cutting new ones for a custom application? Here in the US you can go to any auto parts store and buy a Schrader valve tool.

    Example:

    The standard Schrader valve has the following threads:

    External thread
    • 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)

    Internal thread (to accept the threaded valve core)
    • Metric: 5.30 mm OD × 0.706 mm pitch
    • Imperial: 0.209 in OD × 36 tpi.
