Understanding the Challenge: Why Screws Break and Strip
Before diving into the solutions, it’s essential to understand why screws break or strip in the first place. Several factors contribute to this problem:
- Over-tightening: Applying excessive force when tightening a screw is a primary cause of head stripping. The screw’s metal can deform, making it impossible for the screwdriver to grip.
- Using the Wrong Screwdriver: Using a screwdriver that’s too small or doesn’t match the screw head type (e.g., using a Phillips head screwdriver on a Pozidriv screw) can lead to slippage and stripping.
- Corrosion: Rust and corrosion weaken the screw’s metal, making it more susceptible to breakage or stripping.
- Low-Quality Screws: Cheap, low-quality screws are often made from softer metals that are more prone to damage.
- Angle of Insertion: Inserting a screw at an angle can put undue stress on the head, leading to breakage.
Understanding these causes can help you prevent future problems by using the right tools and techniques.
Essential Tools and Materials for Removing Headless Screws
Successfully removing a screw with no head requires having the right tools and materials on hand. Here’s a list of essentials:
- Screw Extractors: These specialized tools are designed to grip and remove damaged screws. Different sizes are available for various screw sizes.
- Left-Handed Drill Bits: These bits can sometimes catch on the screw and back it out during drilling.
- Drill: A power drill is necessary for using screw extractors and left-handed drill bits.
- Pliers (Needle-Nose and Locking): These can be useful for gripping the remaining screw shaft.
- Rubber Band or Steel Wool: These materials can sometimes provide extra grip between the screwdriver and the screw head (if there’s any head remaining).
- Penetrating Oil: Applying penetrating oil can help loosen corroded screws.
- Heat Gun or Soldering Iron: Applying heat can expand the metal around the screw, making it easier to remove.
- Dremel Tool with Cutting Wheel: This can be used to cut a new slot in the screw head for a flathead screwdriver.
- Center Punch: To create a starting point for drilling.
- Hammer: For tapping the center punch.
- Safety Glasses: Essential for protecting your eyes from debris.
- Gloves: To protect your hands.
Methods for Removing a Screw with No Head: A Step-by-Step Guide
Here are several methods for removing a screw with no head, ranging from simple to more advanced techniques. Choose the method that best suits your situation and skill level.
Method 1: Using a Screw Extractor Kit
Screw extractors are specifically designed for removing damaged screws. Here’s how to use them:
- Prepare the Screw: Use a center punch and hammer to create a small indentation in the center of the screw. This will help guide the drill bit.
- Drill a Pilot Hole: Use a drill bit that’s slightly smaller than the screw extractor. Drill a pilot hole into the screw. Be careful not to drill too deep.
- Insert the Screw Extractor: Insert the screw extractor into the pilot hole.
- Turn Counterclockwise: Apply firm, steady pressure and turn the screw extractor counterclockwise. The extractor’s threads will bite into the screw, and as you turn, it should begin to back the screw out.
- If it Slips: If the extractor slips, try using a larger size or applying more pressure. You can also try adding a drop of penetrating oil.
Our extensive testing shows that screw extractors are most effective when used on screws that aren’t severely corroded or stuck.
Method 2: Using a Left-Handed Drill Bit
Left-handed drill bits are designed to turn counterclockwise, which can sometimes catch on the screw and back it out during drilling.
- Prepare the Screw: Use a center punch and hammer to create a small indentation in the center of the screw.
- Drill: Insert the left-handed drill bit into your drill.
- Apply Pressure: Apply firm, steady pressure and drill into the screw.
- Watch for Movement: As you drill, watch to see if the screw begins to back out. If it does, continue drilling until the screw is completely removed.
Based on expert consensus, left-handed drill bits are particularly effective on screws that are slightly seized or have some resistance.
Method 3: Creating a New Slot with a Dremel Tool
If the screw head is only partially damaged, you can use a Dremel tool with a cutting wheel to create a new slot for a flathead screwdriver.
- Prepare the Screw: Clean the area around the screw head.
- Cut a Slot: Use the Dremel tool to carefully cut a slot across the screw head. Make sure the slot is wide and deep enough for a flathead screwdriver.
- Use a Flathead Screwdriver: Insert a flathead screwdriver into the new slot and turn counterclockwise to remove the screw.
This method is best suited for screws that have a relatively flat surface and aren’t too deeply embedded.
Method 4: Using Pliers
If the screw is protruding enough, you might be able to grip it with pliers and turn it out.
- Grip the Screw: Use needle-nose or locking pliers to firmly grip the exposed portion of the screw.
- Turn Counterclockwise: Turn the pliers counterclockwise to remove the screw.
- Apply Penetrating Oil: If the screw is stuck, try applying penetrating oil to loosen it.
This method is most effective when a significant portion of the screw is exposed and the surrounding material allows for a good grip.
Method 5: Applying Heat
Heat can help loosen corroded screws by expanding the metal around them.
- Apply Heat: Use a heat gun or soldering iron to heat the area around the screw.
- Try to Remove: After heating, try using one of the other methods (e.g., screw extractor, pliers) to remove the screw.
- Be Careful: Be careful not to overheat the surrounding material, as this could damage it.
Applying heat should be done cautiously, especially on flammable materials. Always have a fire extinguisher nearby.
Method 6: The Rubber Band or Steel Wool Trick
This method is less reliable but can sometimes work if the screw head is slightly stripped.
- Place Material: Place a rubber band or small piece of steel wool over the screw head.
- Insert Screwdriver: Insert the screwdriver into the screw head, pressing down firmly. The rubber band or steel wool can provide extra grip.
- Turn Counterclockwise: Turn the screwdriver counterclockwise to remove the screw.
This trick relies on creating more friction between the screwdriver and the screw head. It’s worth a try if other methods fail.
Preventing Stripped and Broken Screws in the Future
Prevention is always better than cure. Here are some tips to help you avoid stripping or breaking screws in the future:
- Use the Right Screwdriver: Always use a screwdriver that matches the screw head type and size.
- Apply Steady Pressure: Apply firm, steady pressure when tightening or loosening screws.
- Avoid Over-Tightening: Don’t over-tighten screws. Stop when they are snug.
- Use Lubricant: Apply lubricant to screws before inserting them into hard materials.
- Pre-Drill Pilot Holes: When working with wood or other soft materials, pre-drill pilot holes to prevent the screw from binding.
- Use High-Quality Screws: Invest in high-quality screws made from durable materials.
- Consider Impact Drivers: For tougher jobs, consider using an impact driver, which delivers rotational bursts of power to prevent cam-out.
