All have tried to near the answer....

Usually Engineers do have some logic & common sense.

1) Nuts and bolts are used for fastening to a tight a seal
properly without leak or to fasten to prevent unnecessary
vibration. For that we have to tighten based on the torque
that a bolt & nut can withstand.

So selecting the bolt for the required application reuires
the customer to specify CLASS like 4.6, 5.8 etc...

Usually class represeent the material composition of the
nut and bolt.... Greater the value specified will have
higher strength...

2) For buying a nut, any person can offord to buy a nut
also together... this is to prevent the ease of assembly...
No need to mention pitch... Only u have to mention the
class and the size like M12, M16....
