Understanding the Problem: Why Screws Break

Before diving into solutions, it’s helpful to understand why screws break in the first place. Several factors can contribute to a damaged screw head:

Overtightening: Applying too much torque can shear off the head, especially with softer metals like brass or aluminum.
Corrosion: Rust and other forms of corrosion weaken the screw, making it more susceptible to breakage.
Stripped Threads: Attempting to force a screw into damaged or mismatched threads can strip the head.
Improper Tools: Using the wrong size or type of screwdriver can easily strip the screw head.
Material Fatigue: Repeated stress or vibration can weaken the screw over time.
Low Quality Screws: Inferior screws often use softer metals and are more prone to breakage.

Recognizing the cause of the breakage can help you choose the most appropriate removal method and prevent future problems.

Essential Tools for Removing Broken Screws

Having the right tools on hand is crucial for successfully removing a screw with a broken head. Here are some of the most useful tools:

Screw Extractors: These specialized tools are designed to bite into the screw head and provide a grip for removal.
Left-Handed Drill Bits: These bits can sometimes grab the screw and unscrew it during drilling.
Penetrating Oil: Helps to loosen corroded screws.
Rubber Band or Steel Wool: Can provide extra grip for stripped screw heads.
Dremel Tool with Cutting Wheel: Useful for creating a slot in the screw head for a flathead screwdriver.
Pliers or Vise-Grips: For gripping the exposed shank of a broken screw.
Hammer and Punch: To tap the screw and break the corrosion.
Heat Gun or Soldering Iron: To heat the screw and expand the metal, loosening it from the surrounding material.

Method 1: Using a Screw Extractor

Screw extractors are specifically designed for removing broken screws. They come in various sizes to match different screw diameters. Here’s how to use one effectively:

Prepare the Screw: Use a center punch to create a pilot hole in the center of the broken screw head. This will help guide the drill bit.
Drill a Pilot Hole: Using a drill bit that’s slightly smaller than the screw extractor, drill a pilot hole into the screw head. Be careful not to drill too deep.
Insert the Screw Extractor: Insert the screw extractor into the pilot hole.
Turn Counterclockwise: Using a tap wrench or a drill with a slow speed and high torque setting, turn the screw extractor counterclockwise. Apply steady pressure.
Remove the Screw: As you turn the extractor, it should bite into the screw head and begin to unscrew it.

Important Tip: Use slow speed and high torque. Avoid applying excessive force, as this can break the screw extractor.

Screw Extractor Variations: Spiral vs. Straight Fluted

Screw extractors come in two main designs: spiral fluted and straight fluted. Spiral fluted extractors tend to provide a more aggressive grip but can also expand the screw, potentially making it harder to remove. Straight fluted extractors are less aggressive but may be more suitable for softer metals. Based on expert consensus, a straight fluted extractor is often preferred for smaller screws to minimize the risk of further damage.

Method 2: Using a Rubber Band or Steel Wool

This method is best for screws with slightly stripped heads. The rubber band or steel wool provides extra grip for the screwdriver.

Place the Material: Place a wide rubber band or a small piece of steel wool over the stripped screw head.
Insert the Screwdriver: Insert the screwdriver into the screw head, pressing down firmly.
Turn Slowly: Turn the screwdriver slowly and apply steady pressure. The rubber band or steel wool should provide enough grip to unscrew the screw.

This method is simple and often surprisingly effective, but it only works if the screw head isn’t too badly damaged.

Method 3: Creating a Slot with a Dremel Tool

If the screw head is too damaged to grip with a screwdriver, you can create a slot using a Dremel tool with a cutting wheel.

Prepare the Area: Clean the area around the screw head.
Cut a Slot: Using the Dremel tool, carefully cut a slot across the screw head. The slot should be wide and deep enough to accommodate a flathead screwdriver.
Remove the Screw: Insert a flathead screwdriver into the slot and turn counterclockwise to remove the screw.

Safety Tip: Wear safety glasses when using a Dremel tool to protect your eyes from flying debris.

Method 4: Using Pliers or Vise-Grips

This method is suitable if the screw head is broken off and a portion of the shank is still exposed.

Grip the Shank: Use pliers or vise-grips to firmly grip the exposed shank of the screw.
Turn Counterclockwise: Turn the pliers or vise-grips counterclockwise to unscrew the screw.

This method can be challenging if the shank is tightly embedded, but it’s often the only option when the screw head is completely gone.

Method 5: Applying Heat

Heat can help loosen corroded screws by expanding the metal. Use a heat gun or soldering iron to apply heat to the screw head.

Apply Heat: Heat the screw head for several minutes.
Try to Remove: After heating, try to remove the screw using one of the other methods described above.

Caution: Be careful when applying heat, as it can damage surrounding materials. Avoid overheating, especially on plastics. Never use this method near flammable materials.

Method 6: Using Penetrating Oil

Penetrating oil can help loosen corroded screws by seeping into the threads and breaking down the rust.

Apply Penetrating Oil: Apply penetrating oil to the screw head and allow it to soak for several hours or even overnight.
Try to Remove: After soaking, try to remove the screw using one of the other methods described above.

Pro Tip: Tapping the screw head lightly with a hammer after applying penetrating oil can help the oil penetrate deeper.

Method 7: Left-Handed Drill Bits

Left-handed drill bits are designed to grab the screw and unscrew it during drilling. This method can be particularly effective for screws that are not too tightly seized.

Select the Correct Size: Choose a left-handed drill bit that is slightly smaller than the screw’s diameter.
Drill into the Screw: Carefully drill into the center of the broken screw head. Apply steady pressure.
Check for Removal: As you drill, the bit may grab the screw and begin to unscrew it. If this happens, stop drilling and remove the screw.

Considerations for Different Materials

The material surrounding the broken screw can significantly impact the removal process. Here’s how to adjust your approach based on the material:

Wood: Wood is relatively soft, so you can often use more aggressive methods without damaging the surrounding material. However, be careful not to strip the wood threads.
Metal: Metal is more durable, but it can also be more challenging to remove screws from. Penetrating oil and heat are often helpful.
Plastic: Plastic is easily damaged by heat and aggressive methods. Use caution and avoid overheating.

Preventing Future Screw Breakage

Preventing screw breakage is always better than dealing with a broken screw. Here are some tips to avoid future problems:

Use the Right Tools: Always use the correct size and type of screwdriver for the screw.
Apply Even Pressure: Apply even pressure when tightening or loosening screws.
Avoid Overtightening: Overtightening is a common cause of screw breakage.
Use Lubricant: Use lubricant when screwing into hard materials.
Pre-Drill Pilot Holes: Pre-drilling pilot holes can prevent screws from breaking, especially in hard materials.
