    ACS Hub Nut / Axle Thread

    Just picked up an old ACS front hub. It's a large flange design, stamped 38 81. Nice.

    The hub came to me without axle nuts/washers. Any idea what thread these are likely to be?

    I think some crafty googling may have given me the answer: 3/8" 26TPI. I'd be grateful if anyone could confirm that!

    I'd recommend just buying a pair of 3/8" 24tpi nuts and a pair of 3/8" 26tpi nuts. I think that most hubs now a 26tpi, but a lot of older hubs were 24tpi. Or maybe it was the other way around.
