Propeller Shaft Nuts

Does anyone out there have or know of a US manufacturer of large Bronze nuts for propeller shafts specifically for Marine applications?

We are looking for nuts for propeller shafts up to 7.50" OD. Also if anyone has or knows of available dimensional information for up to a 5.50" nuts that will also be a great help.

Thanks in advance.
