How to Remove Deck Screws That Are Stripped: A Comprehensive Guide

Dealing with stripped deck screws can be one of the most frustrating aspects of deck maintenance and repair. A stripped screw, where the head is damaged to the point that a screwdriver can no longer grip it, can halt your progress and lead to further damage if not handled correctly. Whether you’re replacing old boards, reinforcing weak spots, or simply making cosmetic improvements, knowing how to remove deck screws that are stripped is an essential skill for any homeowner or DIY enthusiast. This comprehensive guide provides several proven methods to tackle this common problem, ensuring you can get back to enjoying your deck without unnecessary delays or expenses.

Understanding the Problem: Why Screws Strip

Before diving into the solutions, it’s important to understand why screws strip in the first place. Several factors contribute to this issue:

Over-tightening: Applying too much force when driving screws can damage the screw head and the surrounding wood fibers.
Using the wrong screwdriver: Using a screwdriver that doesn’t perfectly match the screw head size and type can cause slippage and stripping.
Corrosion: Exposure to weather elements can cause screws to rust and corrode, weakening the metal and making them more prone to stripping.
Low-quality screws: Cheaper screws are often made from softer metals, which are more susceptible to damage.

Recognizing these causes can help you prevent future stripping incidents.

Essential Tools and Safety Precautions

Before attempting to remove deck screws that are stripped, gather the necessary tools. Having the right equipment on hand can make the process smoother and safer. Here’s a list of essential tools:

Screwdrivers: A variety of sizes and types (Phillips, flathead, square)
Screw extractors: Designed specifically for removing stripped screws
Drill: For use with screw extractors and other methods
Hammer: For tapping tools into place
Pliers or locking pliers (Vise-Grips): For gripping and turning screw heads
Rubber bands or steel wool: To improve screwdriver grip
Penetrating oil: To loosen corroded screws
Safety glasses: To protect your eyes from flying debris
Gloves: To protect your hands and improve grip

Safety should always be your top priority. Wear safety glasses to protect your eyes from flying debris and gloves to improve your grip and prevent injury. Always work in a well-lit area and ensure the work surface is stable.

Methods for Removing Stripped Deck Screws

Here are several methods you can use to remove deck screws that are stripped. The best approach will depend on the severity of the stripping and the tools you have available.

The Rubber Band or Steel Wool Trick

This simple trick can often provide enough extra grip to remove deck screws that are stripped without resorting to more aggressive methods. Place a wide rubber band or a small piece of steel wool over the stripped screw head. Then, insert your screwdriver and apply firm, steady pressure while turning. The rubber band or steel wool fills the gaps in the stripped head, providing a better grip for the screwdriver.

Using a Screw Extractor

A screw extractor is a specialized tool designed specifically for removing stripped screws. Here’s how to use one:

Choose the right size: Select a screw extractor that is slightly smaller than the stripped screw head.
Drill a pilot hole: Use a drill to create a small pilot hole in the center of the stripped screw head. This will help the extractor grip.
Insert the extractor: Place the screw extractor into the pilot hole.
Turn counterclockwise: Apply firm pressure and turn the extractor counterclockwise. The extractor’s threads will grip the screw, allowing you to unscrew it.

Screw extractors are available at most hardware stores and are a reliable option for remove deck screws that are stripped.

Using a Drill

If the screw extractor doesn’t work, you can try drilling the screw out. This method requires a bit more finesse to avoid damaging the surrounding wood.

Use a metal drill bit: Select a drill bit that is slightly smaller than the diameter of the screw’s shaft.
Drill slowly: Start drilling slowly and steadily into the center of the screw head.
Remove the screw head: Continue drilling until the screw head separates from the shaft.
Remove the shaft: Once the head is removed, you can usually remove the remaining shaft with pliers or locking pliers.

Be careful not to damage the surrounding wood when drilling. This method is effective when you need to remove deck screws that are stripped quickly.

Using Pliers or Locking Pliers (Vise-Grips)

If enough of the screw head is still exposed, you can use pliers or locking pliers to grip the head and turn the screw out. This method works best when the screw isn’t deeply embedded in the wood.

Grip the screw head: Securely grip the screw head with the pliers or locking pliers.
Turn counterclockwise: Apply firm pressure and turn the pliers counterclockwise to unscrew the screw.
Wiggle if necessary: If the screw is stuck, try wiggling it back and forth while turning to loosen it.

Locking pliers provide a stronger grip and are particularly useful for stubborn, remove deck screws that are stripped.

Creating a New Slot with a Rotary Tool

If the screw head is too damaged for a screwdriver but still has some material left, you can use a rotary tool (such as a Dremel) to create a new slot for a flathead screwdriver.

Attach a cutting wheel: Attach a small cutting wheel to the rotary tool.
Cut a slot: Carefully cut a slot across the screw head.
Use a flathead screwdriver: Insert a flathead screwdriver into the new slot and turn the screw out.

This method requires a steady hand and can be very effective for remove deck screws that are stripped. [See also: Repairing Damaged Deck Boards]

Applying Heat

If the screw is heavily corroded, applying heat can help loosen it. Use a heat gun or a soldering iron to heat the screw head for a few minutes. The heat will expand the metal, breaking the bond between the screw and the wood.

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

Be careful not to overheat the wood, as this could cause it to scorch or ignite. This method is especially useful to remove deck screws that are stripped due to corrosion.

Using Penetrating Oil

Penetrating oil can help loosen corroded screws by lubricating the threads. Apply penetrating oil to the screw head and let it soak for several hours or even overnight. This will allow the oil to penetrate the threads and break down the corrosion.

Apply penetrating oil: Liberally apply penetrating oil to the screw head.
Let it soak: Allow the oil to soak for several hours or overnight.
Try to remove: After soaking, try to remove the screw using one of the other methods described above.

Penetrating oil is a valuable tool for loosening stubborn screws and can significantly aid in your effort to remove deck screws that are stripped.

Preventing Stripped Screws in the Future

Prevention is always better than cure. Here are some tips to help prevent screws from stripping in the first place:

Use high-quality screws: Invest in high-quality screws made from durable materials.
Use the correct screwdriver: Always use a screwdriver that perfectly matches the screw head size and type.
Apply steady pressure: Apply firm, steady pressure when driving screws to prevent slippage.
Pre-drill holes: Pre-drilling pilot holes can help prevent screws from binding and stripping.
Avoid over-tightening: Be careful not to over-tighten screws, as this can damage the screw head and the surrounding wood fibers.
Use screw wax: Applying screw wax to the threads can make it easier to drive screws and prevent them from stripping.

By following these tips, you can significantly reduce the likelihood of encountering stripped screws in your future deck projects. Regularly inspecting your deck and addressing any signs of corrosion or wear can also help prevent problems before they arise. Knowing how to remove deck screws that are stripped is beneficial, but preventing it is better.

Conclusion

Dealing with stripped deck screws can be a challenging task, but with the right tools and techniques, it’s a problem that can be overcome. Whether you opt for the rubber band trick, a screw extractor, or another method, the key is to be patient and methodical. By following the steps outlined in this guide, you can successfully remove deck screws that are stripped and keep your deck in top condition. Remember to prioritize safety and take preventative measures to avoid stripping screws in the future. With a little effort, you can maintain a beautiful and functional deck for years to come.
