How To Remove A Stripped Screw: Easy Methods

Stripped screws can be a frustrating problem, whether you're tackling a DIY project or a professional repair. A screw becomes stripped when the head is damaged, making it difficult for a screwdriver to grip and turn. This often happens due to applying too much force, using the wrong size screwdriver, or working with old, corroded screws. If you're dealing with a stripped screw, don't panic! There are several methods you can use to remove it without causing further damage. In this comprehensive guide, we’ll explore various techniques, from simple household hacks to specialized tools, to help you extract those stubborn screws. We'll also discuss how to prevent screws from stripping in the first place.

1. Understanding Stripped Screws

Before diving into the solutions, it’s essential to understand why screws strip. When a screw's head is stripped, the grooves or slots that the screwdriver fits into become damaged. This prevents the screwdriver from getting a proper grip, making it impossible to turn the screw. The most common causes of stripped screws include:

• Using the wrong size or type of screwdriver: Using a screwdriver that doesn't fit snugly into the screw head can lead to slippage and damage.
• Applying too much force: Over-tightening a screw or applying excessive pressure while trying to loosen it can strip the head.
• Working with worn or corroded screws: Old screws, especially those exposed to moisture, can become weak and strip easily.
• Using a power drill at high speed: Power tools can quickly strip a screw if not used carefully. Start at a low speed and increase as needed.

2. Simple Methods to Try First

Before resorting to more complex methods, there are a few simple techniques you can try to remove a stripped screw. These methods often work for screws that are only slightly stripped or not tightly lodged.

Rubber Band or Steel Wool

A common household hack involves using a rubber band or steel wool to create a better grip between the screwdriver and the stripped screw head. Here’s how: — Effective Study Strategies: A Comprehensive Guide

1. Place a wide rubber band or a small piece of steel wool over the screw head.
2. Insert the screwdriver into the screw head, pressing firmly.
3. Apply steady pressure and turn the screwdriver slowly. The rubber band or steel wool fills the gaps in the stripped screw head, providing extra friction for the screwdriver to grip.

Using a Wider Screwdriver

Sometimes, a slightly larger screwdriver can grip the screw head better than the original size. If the screw isn’t severely stripped, this method might work.

1. Select a screwdriver that is slightly larger than the one you initially used.
2. Ensure the screwdriver fits snugly into the screw head.
3. Apply steady pressure and turn slowly. If the larger screwdriver can find some purchase on the screw head, it may provide enough leverage to turn the screw.

Hammer and Screwdriver Technique

If the screw is stuck due to rust or corrosion, a gentle hammering technique can help loosen it. This method involves using a hammer to tap the screwdriver into the screw head, helping it grip better.

1. Place the screwdriver into the screw head.
2. Gently tap the back of the screwdriver with a hammer a few times.
3. Apply pressure and turn the screwdriver slowly. The hammering can help break any corrosion or debris that's preventing the screw from turning.

3. Specialized Tools for Stripped Screws

When simple methods fail, specialized tools can provide the extra grip and leverage needed to remove stripped screws. These tools are designed specifically for this purpose and can save you a lot of time and effort.

Screw Extractors

Screw extractors, also known as screw removal tools, are designed to grip and remove damaged screws. They typically come in sets with various sizes to match different screw heads. There are two main types of screw extractors:

• Spiral Flute Extractors: These extractors have a spiral design that digs into the screw head as you turn counterclockwise. This creates a strong grip, allowing you to back out the screw.
• Straight Flute Extractors: These have a straight, tapered design that wedges into the screw head. They require a bit more care to use but can be very effective.

Here’s how to use a screw extractor:

1. Create a Pilot Hole: Use a center punch and hammer to make a small indentation in the center of the stripped screw head. This helps guide the drill bit.
2. Drill a Pilot Hole: Use a drill with a drill bit slightly smaller than the screw extractor. Drill a hole into the screw head. The depth of the hole should match the extractor's instructions.
3. Insert the Screw Extractor: Insert the screw extractor into the drilled hole. For spiral flute extractors, turn counterclockwise. For straight flute extractors, tap the extractor into the hole with a hammer to ensure a tight fit.
4. Turn and Remove: Use a wrench or tap handle to turn the extractor counterclockwise. The extractor will grip the screw head and, with steady pressure, back it out.

Impact Drivers

Impact drivers are powerful tools that deliver both rotational force and hammering action. This combination is highly effective for loosening stubborn screws, including stripped ones.

1. Select the appropriate bit for the stripped screw.
2. Insert the bit into the impact driver.
3. Place the bit firmly into the screw head.
4. Apply pressure and use the impact driver to turn the screw counterclockwise. The hammering action helps break any corrosion or resistance, while the rotational force backs out the screw.

Locking Pliers (Vise-Grips)

Locking pliers, also known as Vise-Grips, can be used to grip the head of a stripped screw and turn it. This method is particularly useful if the screw head is protruding enough to get a good grip.

1. Adjust the locking pliers to fit tightly around the screw head.
2. Lock the pliers in place, ensuring a firm grip.
3. Turn the pliers counterclockwise to unscrew the stripped screw. Apply steady pressure to avoid slipping.

4. Advanced Techniques for Severely Stripped Screws

For screws that are severely stripped or broken, more advanced techniques may be necessary. These methods often require specialized tools and a bit of extra care.

Cutting a New Slot

If the screw head is still somewhat intact, you can cut a new slot into it using a rotary tool or a hacksaw. This new slot can then be used with a flathead screwdriver to turn the screw.

1. Using a Rotary Tool: Attach a cutting disc to a rotary tool (such as a Dremel).
2. Cut a Slot: Carefully cut a slot across the screw head. Make sure the slot is deep and wide enough for a flathead screwdriver.
3. Remove the Screw: Insert a flathead screwdriver into the new slot and turn counterclockwise.

If you don't have a rotary tool, you can use a hacksaw to carefully cut a slot in the screw head. This method requires more precision and patience.

Welding a Nut

For larger screws or bolts that are severely stripped, welding a nut to the screw head can provide a solid grip. This method requires welding equipment and some experience. — Kaiser Northern CA Member Services Number: Find It Fast!

1. Place a nut over the stripped screw head.
2. Weld the nut to the screw head, creating a strong bond.
3. Use a wrench to turn the nut counterclockwise, removing the screw. The welded nut provides a solid point of contact for turning the screw.

Drilling Out the Screw

As a last resort, you can drill out the screw. This method involves using a drill to destroy the screw head and remove the remaining shaft. However, it should be approached with caution, as it can damage the surrounding material if not done carefully.

1. Use a Center Punch: Create a pilot hole in the center of the screw head using a center punch and hammer.
2. Drill with a Small Bit: Start with a drill bit that is smaller than the screw’s core diameter. Drill through the screw head.
3. Increase Bit Size: Gradually increase the drill bit size until the screw head separates from the shaft.
4. Remove the Shaft: Once the head is removed, you can often remove the remaining shaft with pliers or by using a screw extractor. If the shaft is deeply embedded, you may need to use a specialized screw extractor designed for broken screws.

5. Preventing Stripped Screws

Prevention is always better than cure. Taking a few precautions can help you avoid stripping screws in the first place. Here are some tips to keep in mind:

• Use the Right Screwdriver: Always use a screwdriver that fits the screw head snugly. The correct size and type of screwdriver will prevent slippage and reduce the risk of stripping.
• Apply Steady Pressure: When turning a screw, apply steady, even pressure. Avoid pressing too hard, which can damage the screw head.
• Start at a Low Speed: If using a power drill or impact driver, start at a low speed and increase as needed. This gives you more control and reduces the chance of stripping the screw.
• Use Lubrication: For old or corroded screws, apply a small amount of lubricant (such as penetrating oil) to the threads. This can help loosen the screw and make it easier to turn.
• Replace Worn Screws: If you notice that a screw is worn or damaged, replace it before it strips. Using fresh, high-quality screws can make a big difference.

6. When to Call a Professional

While many stripped screw issues can be resolved with DIY methods, there are situations where it’s best to call a professional. If you’ve tried several techniques and still can’t remove the screw, or if you’re dealing with delicate or expensive materials, it’s often worth hiring a handyman or contractor. Professionals have the tools and expertise to handle complex screw removal without causing damage.
