DeWalt drill chuck shaft, inner thread spacing?

Never mind. The inner threaded part helps keep the Chuck from coming
off and is reverse threaded, so I could not use it anyway.

Sorry if any reply was already on the way.

That's so the chuck doesn't unscrew when you're running the drill in
reverse.

It'll be a left-hand thread, which is probably best obtained from DeWalt ...

If you're talking about the threads for the small screw that goes through
the center of the bottom of the chuck and into the end of the arbor, I
don't know what the thread size is, but every drill I've ever seen uses
a left-hand thread there.

Often wrong, never in doubt.
