3/8" 26 tpi Gripfast???
Do the 3/8 26 tpi Gripfast nuts fit Sturmey Archer 3 speed hub axles? Trying to figure out if 3/8" 26, and 13/32" 26 are actually 2 separate sizes.

Bump.
LBS no help.
Still trying to find out if they are two distinct sizes as numerically indicated, or only different in nomenclature for the US market.

Have you not tried threading one on to your existing Raleighs? Proof is in the pudding. Or if you don't have one in hand, maybe you should just ask the board to buy what you need?

3/8"-26, and 13/32"-26 are 2 separate sizes - there is .03125" difference in diameter.
26 TPI is an old British motorcycle thread standard - some probably had a lathe that would only do 26 TPI thread - it is used on all sorts of bolt diameters, from very small (where it is a very coarse thread) to quite large (where it is a very fine thread).
