How to Remove Damaged or Stripped Screws

Removing a stripped screw can be a challenging task, but with the right approach and a few simple tools, it is possible to overcome this common DIY hurdle. Whether you are trying to remove stainless steel deck screws or just plain wood screws. 

 

To successfully remove a stripped screw, it is crucial to understand why it happened in the first place. Screws can become stripped when their heads are damaged due to improper tools or excessive force.
If there was ever a case for prevention being better than cure, this is it!
Maintain the tips of manual screw drivers, and use fresh bits in drill drivers and impact drivers.

Once a screw head is stripped, traditional screwdrivers become ineffective, and alternative methods must be employed to grip and turn the screw. The following techniques will address different approaches to removing the stripped screw, ensuring the job can be done efficiently and effectively.

 

Common methods to remove stripped screws

 

1. Use a Different Driver

For a stripped Phillips head screw, try using a manual flathead screwdriver. Angle the blade into the screw head, force it down hard, and after about 1/4-inch of the screw has been exposed, clamp locking pliers to the sides of the screw head. Then, turn the screw the rest of the way out.

 

2. Use Pliers

Bypass the stripped screw head and grip the screw with a pair of locking pliers or vice grips. Turn the adjustment screw on the pliers, then clamp down on the screw head either from the top or the sides. Turn the screw counter-clockwise until it releases from the material. For screws that are flush or embedded in wood, create a few shallow grooves next to the screw head to improve the grip.

 

3. Use a Larger Driver

Gently tap a manual screwdriver into the screw head using a light hammer. This helps seat the screwdriver tip slightly deeper into the screw for a better grip. Lean hard into the drill or screwdriver and turn counter-clockwise. Old, rounded-down drill bits or screwdrivers are beneficial because they have flatter tips, providing more surface contact between the tip and the screw head.

 

4. Use a Screwdriver

Use a normal screwdriver to remove the stripped screw instead of using an electric drill and driver bit. A manual screwdriver gives you more torque and control than an electric drill, making it easier to lean into the screw and add pressure without the risk of further stripping the screw.

 

5. Tap With a Hammer

Gently tap a manual screwdriver into the screw head using a light hammer. This helps seat the screwdriver tip slightly deeper into the screw for a better grip. Use a manual screwdriver that is properly sized for the screw, tap the back of the screwdriver handle with a hammer three or four times, and then turn the screw to remove it.

 

6. Cut a Slot

Cut a slot into the screw head with an electric tool, such as a rotary cutting tool or a multi-tool fitted with a metal blade. Turn on the tool, and wearing safety glasses, hold the tool parallel with the material and cut a shallow groove in the screw head. Place the tip of a flat-head screwdriver in the groove, press hard, and turn counter-clockwise.

 

7. Use a Screw Extractor

Using a screw extractor kit is the best way to remove a stripped screw if other methods aren't working. A screw extractor kit includes two special drill bits: one with the correct diameter to receive the extractor, and another with reverse threads. Use a small drill bit to drill a hole in the screw and then switch to the reverse drill bit to remove the screw. Always use a centre punch to help start the drill in the correct position.

 

How to Remove a Stripped Screw from Different Materials

Consider the type of material the screw is stuck in, whether wood, metal, or plastic, as different materials may require different techniques and supplies.

 

Remove Stripped Screw from Metal

To remove a stripped screw from metal, first, tap it with a small hammer to break up any rust. Then apply penetrating oil and use a screw extractor kit to help remove the rusted screw.

 

Remove Stripped Screw from Wood

When working with wood, cover the area surrounding the screw with tape to prevent damage. If the screw head is below the surface, use a screw extractor or extractor pliers to access the screw head.

 

Remove Stripped Screw from the Wall

If a stripped screw is embedded in the wall, turn it counter-clockwise with pliers. If the screw head is flush or below the surface, dig into the drywall with a flathead screwdriver to give pliers access to the screw head.

 

How to Avoid Stripping Screws

Preventing a stripped screw is the best way to avoid the frustration of removing one:

• Use Torx drive screws as they are very difficult to strip
• Opt for a screwdriver or bit with a sharp, square tip instead of a rounded one.
• Always use a screwdriver or bit that matches the screw size.
• Choose a higher-quality screw, as some are made from softer, lower-quality metal that can strip more easily.
• Don't apply excessive force when driving the screw.
• Hold the driver perpendicular to the screw; avoid holding it at an angle.
• For better torque control, use a manual screwdriver if possible.
• Drill pilot holes in wood to reduce strain on the screw.
• When the driver starts slipping on the screw, stop turning to prevent further stripping.

 

With these helpful tips and techniques, you'll be well-equipped to handle stripped screws and get back to your DIY project quickly. Remember to stay patient and persistent, and before you know it, that stubborn screw will be out, and you'll be well on your way to completing your project.
