Is the nut in this part 1/4-28? It is replacing a nut with that exact size, which is nearly impossible to find in hardware stores.

Hi, Jim. The thread specifications are not available. The threads are not a standard type but proprietary to Sta-Rite.

I have a cristal-flo filter and need the black handle to the clamp ring assembly. Are these handles universal on sand filters?

Yes this is the correct black handle for your cristal-flo clamp.
