Does anyone know if npt thread is designed such that it will self tap give the right diameter hole? I’m looking to insert several barbs in quite a few blocks, aluminum. I’m not realy interested in gluing them in or "lathing" the thread down and forcing it in. this is aluminum so it wont solder. If brass npt will self tap, at what size hole?
