The opening in the hex screw that holds the rear brake cable has become much looser than it used to be. What is the name of the part so I can order another one? (Hopefully they have some made of harder steel.)

It is simply a clamp bolt and the question is whether it holds the
brake cable tightly when it is tightened, If it does than I shouldn't
worry about it.

As the bolt should be clamping the cable between a flange or washer on
the bolt and the brake arm itself. When it is tightened it shouldn't
move at all.

Your picture looks a bit strange, but maybe it is the perspective. See

from a slightly different angle.

If that clamp bolt gets enlarged much more so my hex wrench slips, it will definitely be a big problem.

Are you positive you're using the correct size hex wrench? Some people
mistakenly grab a U.S. (inch) wrench and use it on metric screws that it
_almost_ fits.

The bike is a Huffy Nighthawk Model 56347. The manual does not specify whether it uses American or metric sizes.

I have just a set of American hex wrenches but could get a set of metric wrenches and see if one of them fits the clamp bolt better.

The price of "Allen" wrench sets sufficient to fix a bicycle is
minute, in fact you may not be able to even buy a set small enough :-)
My entire bicycle uses 5 different size Allen wrenches,

Amazon has an set 8 wrench (metric) set for $4.99 and if you hang
around the "Cheap Chinese Stuff" shops that I do it will be even
cheaper.

LOL! ;) I remember one ride I was on (going somewhere here in town) where I had forgot my tool kit and needed a hex key to tighten something. I went into a dollar store and bought a set of hex keys to use to tighten the item that needed tightening. Guess what? When i went to tighten the bolt the hex key round off so much it would not grip the bolt. Some Chinese made stuff must not have any tempering done to it at all. Now I pay the extra and by decent quality tools even if they're not top of the line ones.
