Just measured thread with Whitworth thread gauge and it is 16 threads per inch.
Diameter of thread is 0.621 with my micrometer (which is nearly 0.625 inch = 5/8 inch.
My Austin nut across flats measures 13/16 inch by calliper (0.8125 inch). (note 7/16 given in my table as 0.82 AF).
Ah just seen table someone made........stub axle bearing nut 5/8 inch Austin special 16 tpi whitworth form...55 degree thread angle.
I note that 7/16W is slightly larger (0.82 inch) spanner size than 13/16 but would do?
