Lightweight swinging arm spindle nut

Forums

Hello,

anyone know the thread for the swinging arm spindle nut, mine looks a bit bashed and I can not be sure of measuring with thread gauge.

Thanks

Andrew

Hi Andrew,

The stud fitted to my navigator is 7/16" BSF, 18 TPI.

Thanls Dave,

I thought it might be BSC, but will look at BSF 18.

I agree with this- just checked the 1959 Jubilee and it is definitely 7/16" BSF, 18TPI.
