I have machined out a new axle for some track hubs I have, matched the threading and key way... but added length so I could space it for 130mm drops... but I now want to use these hubs for a multi-speed build, so I will be threading a freewheel 4 or 5sp cassette on it. My question is their a sufficient number of threads on a track hub to hold a cassette properly?

And they are HF c-record hubs and cant seem to locate a road set to build with.

also I like the Idea of the bolt, versus QR.
