Margnors isn't a general hardware store. They stock some hardware, and there is a plumbers' supplier next door, but their speciality is fastners. I've taken them all sorts of strange threads -- last time we were in your country they sold me b'zarre fine-thread metric bolts for the suspension of the Samurai, so I could get it through NCT -- and I've never seen them miss.

For taps and dies, they'll be the dog's.
