OFFICE MEMO MGB nuts Date:6/13/94
>My '65 MGB tourer (roadster) has a banjo rear axle
with axle nuts of a size I cannot find among my collection of SAE and
metric sizes.
I am assuming you mean you can't find wrenches to fit the nuts.
>These nuts hold the oil seals and wheel bearings in
place. Are these relics of MG's Whitworth sizing in earlier series?
I don't know specifically about MG's, but my guess is they are British Standard
Fine thread nuts and bolts, which are sometimes incorrectly called "Whitworth"
because they use the same "Whitworth" threadform as the Whitworth coarse thread
series. My '51 Jag has many BSF (Whitworth) nuts and bolts. I used to get by
with using metric wrenches until I found some British ones.
>Are sockets available to fit these? are replacement (non-Baroque) nuts
available?
Sockets, combination wrenches, and I think some sizes of BSF nuts are available
from Moss Motors in Goleta, CA 1-800-235-6954
Caution: do not put an SAE nut onto a BSF bolt, because even though the
diameter is the same, the thread angle and number of threads per inch is
different. But you can usually substitute the nut and bolt together - BSF for
SAE.
Anyone else interested in reading my treatise on the Whitworth Thread System?
If so I'll post it.
