Method 1: Using a Screw Extractor Kit

Screw extractor kits are specifically designed to remove broken screws and bolts. They typically include a set of drill bits and extractors of varying sizes. Here’s a step-by-step guide to using a screw extractor:

1. **Prepare the Screw:** Use a center punch to create a small indentation in the center of the broken screw. This will help guide the drill bit and prevent it from slipping.
2. **Drill a Pilot Hole:** Select a drill bit that is slightly smaller than the diameter of the screw extractor. Carefully drill a pilot hole into the center of the broken screw. Maintain a steady pressure and avoid applying excessive force.
3. **Insert the Screw Extractor:** Choose the appropriate size screw extractor for the pilot hole. Insert the extractor into the hole and gently tap it with a hammer to ensure it’s securely seated.
4. **Turn the Extractor:** Using a wrench or pliers, slowly turn the screw extractor counter-clockwise. Apply steady pressure and avoid jerking motions. The extractor should grip the screw and begin to back it out.
5. **Remove the Screw:** Continue turning the extractor until the broken screw is completely removed. If the screw is particularly stubborn, apply penetrating oil and allow it to soak for a few minutes before attempting to remove it again.

**Pro Tip:** To avoid breaking the screw extractor, use a slow, steady turning motion and avoid applying excessive force. If the extractor slips, try using a larger size or applying more penetrating oil.

Method 2: Using a Left-Handed Drill Bit

Left-handed drill bits are designed to turn counter-clockwise. In some cases, the act of drilling with a left-handed bit can be enough to grip the broken screw and back it out. Here’s how to use this method:

1. **Prepare the Screw:** As with the screw extractor method, start by using a center punch to create a small indentation in the center of the broken screw.
2. **Select the Drill Bit:** Choose a left-handed drill bit that is slightly smaller than the diameter of the screw.
3. **Drill Carefully:** Position the drill bit on the indentation and begin drilling at a slow speed. Apply steady pressure and maintain a straight angle.
4. **Observe and React:** As you drill, pay close attention to whether the drill bit is gripping the screw. If the screw starts to turn with the drill bit, continue drilling until it is completely removed. If the drill bit doesn’t grip the screw, you may need to try a different method.

**Our Experience Shows:** This method works best on screws that are not tightly seized or heavily corroded. It’s also more effective on softer metals.

Method 3: Creating a Slot with a Dremel Tool

If the screw head is still partially intact, you can use a Dremel tool with a cutting wheel to create a slot for a flathead screwdriver. This method requires a steady hand and careful attention to avoid damaging the surrounding material.

1. **Prepare the Area:** Clean the area around the broken screw to remove any debris or obstructions.
2. **Create the Slot:** Using a Dremel tool with a cutting wheel attachment, carefully create a slot across the top of the broken screw head. Make the slot deep enough to accommodate a flathead screwdriver.
3. **Remove the Screw:** Insert a flathead screwdriver into the slot and turn it counter-clockwise. Apply steady pressure and avoid stripping the slot. If the screw is stubborn, try tapping the screwdriver with a hammer to help loosen it.

**Important Note:** Wear safety glasses when using a Dremel tool to protect your eyes from flying debris.

Method 4: Using Pliers or Locking Pliers

If a portion of the screw head is still protruding, you may be able to grip it with pliers or locking pliers and turn it out. This method is best suited for screws that are not tightly seized or deeply embedded.

1. **Grip the Screw:** Use pliers or locking pliers to firmly grip the exposed portion of the screw head.
2. **Turn the Screw:** Slowly turn the pliers counter-clockwise. Apply steady pressure and avoid slipping. If the screw is stubborn, try applying penetrating oil and allowing it to soak for a few minutes before attempting to remove it again.

**Expert Tip:** Locking pliers provide a more secure grip than regular pliers, making them a better choice for this method.

Method 5: The Rubber Band or Steel Wool Trick

This method is useful when the screw head is stripped, preventing a screwdriver from gripping properly. Placing a rubber band or a small piece of steel wool between the screwdriver and the screw head can provide extra friction and improve grip.

1. **Prepare the Screw:** Clean the screw head to remove any debris or grease.
2. **Insert the Material:** Place a rubber band or a small piece of steel wool over the screw head.
3. **Insert the Screwdriver:** Insert the screwdriver into the screw head, pressing firmly to engage the rubber band or steel wool.
4. **Turn the Screw:** Turn the screwdriver counter-clockwise. Apply steady pressure and avoid slipping. The extra friction provided by the rubber band or steel wool may be enough to grip the screw and back it out.

**Based on Expert Consensus:** This method is most effective on screws that are not tightly seized or heavily corroded.

Method 6: Heat Application

Applying heat can help loosen corroded or seized screws by expanding the metal and breaking the bond between the screw and the surrounding material. This method should be used with caution, as excessive heat can damage the surrounding material or create a fire hazard.

1. **Apply Heat:** Use a heat gun or a soldering iron to apply heat to the screw head. Heat the screw for a few seconds, then allow it to cool slightly.
2. **Attempt Removal:** After heating and cooling the screw, try removing it using one of the methods described above. The heat may have loosened the screw enough to allow it to be removed more easily.

**Safety First:** Always wear gloves and eye protection when working with heat. Avoid overheating the screw, as this can damage the surrounding material.
