What tap for a Niles stopper?

[Carl Fisher]

I've come to the conclusion that I need a tap for the niles bottle stoppers. Can anyone confirm the tap size for me really quick before I find one to order?

Thanks!

Nevermind, found several locations after some searching. Found a MT2 mandrel that self taps which will work perfect.

3/8 x 16tpi

Thanks

5/16 drill bit works best also. You probably already knew that, but just in case. :biggrin:

Yep, that's it.
