As for the list of machines, you can use just about anything, it all comes down to how long the process will take.

As for the quality norms, they are dependent on the type of bolt or nut your making, you need to look that up in any bolt chart, they are graded on the chart and will explain (in detail) the quality norms.

If you want to earn money with a bots and nuts factory then you should consider to pay for experience and hire a consultant, if it is a student project then you should go to a library and consult the corresponding books. same if you put the question simply by curiosity.

The subject is sooooooooooooo large that a forum as CR4 even by best will would not be able to fulfill you needs.
