Nut size?

[Graham Honnor]

Hello All
I am doing the rear hubs on my '37 Ruby axle and wondered if anyone could tell me what size the thin nut is that holds the inner half of the hub on please.
My largest Whitworth socket is 3/4" which fits the half shaft nut but I'll need a box spanner to do the thin nut or a deep socket.
Many thanks as always
Graham.

Hi Graham,

The new nuts I have here need a 1" Whitworth spanner to fit them. We make a special flat spanner here to fit them.

This is what we make

Hello Hedd

Yes, I intend to do similar with the half shaft nut but I didn't think the thin nut needed the same treatment?
I already had a 3/4" whit socket for the halfshaft nut and I now have a 1" whit box spanner for the thin nut which
I hope will be adequate with a suitably long tommy bar.
We'll see how it goes at the weekend, and in time, if the sealed bearings + felts keep the oil off my shoes.

Thanks for your reply.

Graham.
