Ron,
The thread is 5/8" BSP (British Standard Pipe) which is extremely similar size & pitch as 16mm. BSP threads are usually tapered however the JH tank uses a parallel thread with a fibre washer.
I just replaced the drain plug in my tank as it was brass and had fractured, I had no luck in getting an off the shelf plug to fit exactly, so I bought a standard 16mm sump plug (very close fit) and got an engineering shop to run a 5/8" BSP dye nut over it, you then use a fibre or copper washer and your done.
Cheers Steve
