The proper tool to remove a stripped fastener is __________.

• A. Hammer
• B. Pliers
• C. Safety goggles
• D. Extractor kit

Answer: (D)

When a fastener is stripped, you need a tool that can bite into what's left of the damaged head and provide turning force without relying on the original driver shape. An extractor kit is designed for this situation: you drill into the center of the damaged head, then use a reverse-threaded extractor that bites as you turn counterclockwise, allowing the fastener to back out. This approach creates a new grip inside the fastener and lets you remove it cleanly. Using a hammer can further deform the head, pliers may slip and won’t deliver enough torque, and safety goggles, while important for eye protection, don’t remove or loosen the fastener by themselves.
