Nope. The "NAS" number has changed but the same old bolt is still

That conveniently ignores the fact that a 1/4"-28 screw isn't an M6x1.0 screw. There is no metric "internal wrenching bolt" so there's no such bolt on a recently manufactured bicycle (even a pretend bicycle like a Huffy).

Don't be dissin my bike. :-)

For the price, Huffy makes a fine bike.

I've also had a fine Raleigh 3 speed that I logged thousands of miles with.
