I take it that the american threads fit right into 1/2 inch BSP hardware

Yep they do. You might want to use a bit of ptfe tape to seal them. There's a little bit of stripping of the QD thread when you put it into a male bsp fitting, but it's hardly noticable, and shouldn't be of much concern as long as you don't remove the QD's frequently :thumb:
