Looking at pic 1 the plate seems to have "a thread`s width" bend to it. Maybe it`s intended, maybe not.It could be the angle the camera was that but that bolt looks stressed, or bent. Better to replace both. If it is a stud and not a bolt, it should screw right out, if it is a bolt , a tap with a hammer should knock it loose. pete
Should really be double nutted. As for thread, are there any original stuffing boxes left? The Fastenal suggestion is the best I've heard.
On my boat the stuffing box (1983) is original. Why double nut? Those nuts have lots of back pressure and won't back off. Even if both loosened there would not be a catastrophic leak.
I recently replaced mine. They were BSW 1/2-12.

Thank-you everyone -it is a 1/2-12 inch standard. I also need to add 2-3 layers of flax. Does anyone know the correct size? It's a 77 Marine Trader 40DC
Diver Dave: You say it should be silicon bronze nuts and not Stainless?
THANK YOU!
