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
