Which tool would you use to create internal threads in a hole?

• A. Tap
• B. Die
• C. Rivet Gun
• D. Cordless Drill

Answer: (A)

Creating internal threads inside a hole requires a tool that cuts threads on the inside surface. A tap is designed for this purpose. You drill the hole to the correct pilot size, then use the tap with a wrench to cut the threads along the hole walls, producing matching internal threads for a bolt or screw. Cutting fluid helps the tool cut smoothly, and you turn it gradually to avoid breaking the tap. A die is used for external threads on a rod, not inside a hole. A rivet gun joins pieces with rivets and involves no threading. A cordless drill can make holes or drive fasteners, but it doesn’t cut internal threads by itself.
