10-40 thread of rimfire z1 plugs

[fumopuc]

Hi everybody, a stupid question of an European guy, is this the right definition of a Rimfire Viper Z1 to 3 spark plug  thread ?

Hi Achim,
You are correct. The plugs are 10-40 thread. The O.D. is .190 (4.826 mm) and the pitch is 40 threads per inch.

Hi George, thank you very much for your confirmation.
Sometimes I get a bit lost between the imperial and our metric world.
I have seen that Roy from S/S does offer the tap also, not only the plugs, so a source is also known.
Currently it is for a CAD Fusion360 project only, but you never know.

That's not to bad. It's just a little bigger than a 2 BA and a little smaller then M5.
