Thread size help

[catman275]

Hi all,
I need to know a nut size. The thread is on a stud. part number 217977 in the series 3 book.
It fits in the rear of the transfer box and holds the transmission brake plate.
I just want the outer thread size so I can get a nut on them.
I have searched my box of surplus but no joy.
Thanks Peter
