If they are self tapping screws, the drill bit is as thick as the solid barrel of the screw. If you want the screw to go through easily to have a nut on the other side, then the drill bit is slightly larger than thread size.
A refers to the external thread of a screw or bolt. B means internal thread, specified for nuts and inserts. For example a 2A bolt uses a 2B nut
Picture a nut on a screw. You are holding the nut so it can't turn, but allow it to go up and down the screw. The screw is restrained so it can turn, but not move back and forth. As you turn the screw one way and the other, the nut will move up and down the screw. That is a trivial example of one very common screw thread mechanism.
The split nut, also known as half nut enables thread cutting on a lathe. It is engaged around the lead screw (which is housed in the apron attached to the saddle) and moves the saddle in the required direction at the required pitch.
A screw has threads that will grip into the material or will thread into a Nut. A Nail is driven straight into the material and thus it can work loose under certain load conditions. Both are generally referred to as Fasteners in America.
Is a hub nut reverse thread
what are various possible reasons nut not entering in thread
when a spiral groove is cut over a hole, then it is nut thread. when a spiral groove is cut over a shaft, then it is screw thread.
A thread rolling machine is used to cut threads on round metal bars, in order to take the screw thread of a nut (as in a nut and bolt).

Go to a hardware store and buy a nut with that thread and try it.
The best way is to "double nut" them. Thread one nut halfway down the bolt, then thread another down against that one. Use a wrench on the first (bottom) nut to back the bolt out.

With the tool, while they call this a flywheel puller it is a reverse thread nut, with a normal thread bolt in the center. After removing the nut holding on the mag, reverse thread the tool , then tighten the bolt in the center, off comes the mag.
