【Product Details】
🔍 You’ll need this in these situations!
Broken Screw Heads: The screw head has snapped off and is stuck in the hole, making it impossible to remove.

Stripped Screws: The Phillips or hex head of the screw has been stripped, making it unable to bear load.

Severely Rusted Bolts: Bolts that have become rusted and seized due to prolonged exposure to the outdoors or damp environments.

🛠️ How It Works: Grips in the Opposite Direction for Easy Removal
Features a reverse-thread (counterclockwise) design. When you drill the extractor counterclockwise into the hole containing the broken screw, the threads grip tightly against the inner wall of the hole. As you rotate, the broken screw is pulled out by the counteracting force.

🚀 Instructions (How to Use)
Drill a pilot hole: Using a drill bit, drill a pilot hole of appropriate size at the center of the broken wire (we recommend referring to the dimensions of the extractor’s tip).

Insert the extractor: Insert the extractor of the corresponding size into the pilot hole.

Rotate Counterclockwise: Using a cordless drill or wrench, slowly rotate counterclockwise. The extractor will grip the broken screw.

Remove the Broken Screw: Continue rotating counterclockwise; the broken screw will be unscrewed.

Tight Spaces: If space is limited, attach the self-locking extension rod before proceeding.

⚠️ Important Reminder
Keep the drill bit perpendicular to the screw during operation to prevent slipping due to tilting.

We recommend using a low-speed setting with a cordless drill to avoid breaking the extractor due to excessive force.

After use, apply rust-preventative oil and store in a dry place.
