Answer 2

B. A die

Step-by-step explanation:

A die is an indispensable tool when working with screws, nails and nuts.

This is because a die is the tool that has a "mold" for a part that needs to be produced. When used, the die fixes strongly on a base that is inferred from the screw, forming a strictly rigid set and thus promoting the cutting of new external threads on a bolt.
