11/32" AF is the direct equivalent to 1/8" Whitworth
The locknut size on the tops of Commando Concentric
throttle and choke cables, it would seem.
I bought a long and strong 11/32" version to do the 1/8"W tappet block nuts on prewar/just postwar Enfields.
Fits them perfectly. Long enough to be able to snug them up comfortably.https://i.ebayimg.com/images/g/Ca4AAOSw0G1gDVfn/s-l1600.png
*(Actually they'd be a BS/cycle thread size, but I haven't quite come to terms with what those may be called.)
have become quite difficult to source, at least hereabouts)(and even smaller sizes).
I've seen it writ that anything that is xyz/32" sized in AF is a direct replacement for the hex sizes in the Whitworth
/Cycle Thread world. I think that means that xyz will only ever be odd numbers.
