I would only add that only top quality taps should be used as some of these Chinese cheapos are capable of opening up the thread form way too much. This could lead to threads being stripped at the correct torque setting.
Threads in our cars are to specified class sizes, and some of the Chinese taps are at the bottom of the class.
