Which tool is used to create or repair internal threads, such as those needed for bolts?

Tap
Die
Reamer
Milling cutter

The correct answer is: Tap

To create or repair internal threads necessary for bolts, the appropriate tool is a tap. A tap is specifically designed to cut threads into the interior of a pre-drilled hole, allowing for the insertion of screws or bolts. When using a tap, it is essential to ensure that the correct size and thread pitch correspond to the specifications required for the bolt being used. The other tools mentioned have different functions: a die is used for creating external threads on materials, a reamer is employed to enlarge or finish existing holes to precise dimensions, and a milling cutter is a versatile tool primarily for shaping and cutting materials. Therefore, the function of a tap as a threading tool is what makes it the correct answer for this question.
