question 13
which tool would be best used to make external threads on a steel rod?
select one:

A die is a tool specifically used for cutting external threads on cylindrical work - pieces like a steel rod. A tap is for creating internal threads. A thread maker is a more general and less precise term. A thread file is mainly for cleaning or finishing threads, not for creating them.

d. A die
