How To Fix a Stripped Screw Hole

Updated
Fixing a stripped screw hole is easier than you think.

Fixing a stripped screw hole is crucial if you want to reuse the hole. It takes a bit of ingenuity and creativity to achieve satisfactory results, but it can be done.

If you have a shortage of time or limited funds, there are quick fixes you can do. We show you how to fix a stripped screw hole in a few easy steps.

Fixing a Stripped Screw Hole

There are three ways to easily fix a stripped screw hole. First, take toothpicks and insert them into the stripped screw hole. Apply wood glue and gently tap them in place. Snap off the excess so they sit flush with the wall and allow the glue to dry. Now you can insert your screw and it will bite into the wood.


3 Ways To Fix a Stripped Screw Hole

There are 3 main ways to fix a stripped screw hole. They range from easy to challenging, but they are all effective at sorting out the problem.

A Quick Fix With Toothpicks

This is an easy cheat to fix a stripped screw hole. You can also perform this using used matchsticks and cocktail sticks.

1. Plug the Hole

Partially insert as many toothpicks into the stripped screw hole as it will take. You should find 2 or 3 will suffice. Make sure they fit snuggly.

2. Wood Glue

Add a few drops of wood glue to the sticks and spread it evenly, coating the exposed sections. Use your finger or cotton swabs to perform this task.

3. Insert Into the Hole

Gently tap the glue-coated sticks into the wall with a hammer, making sure there are no gaps. If you need to add more glue, do so. When the hole offers resistance, and the sticks will no longer move, give them a firm whack with the hammer to snap off the excess, leaving them flush with the wall.

4. Allow To Dry

Leave a gap of 1 hour to allow the wood glue to dry and for the sticks to fuse inside the stripped hole. The wooden sticks will create the resistance the new screw needs to gain purchase in the wall.

Check the drying times of your particular wood glue as it may differ.

5. Insert the Screw

Once the glue has set, insert the screw, turning clockwise until the head of the screw is sitting flush with the wall.

Using Plastic Wall Plugs

This also an easy way to mend a stripped screw hole.

1. Buy Wall Plugs

Purchase plastic wall plugs from your local hardware store. To get the correct size, take your chosen screw with you to the store and make sure they match for length and diameter.

2. Bore a New Hole

If the plugs don’t fit the original hole, you’ll need to drill a wider one. Make sure the new opening is 1 to 2 centimeters longer to ensure the wall plug fits the hole.

If it does fit, skip the drilling and insert the wall plug into the old opening.

3. Insert the Wall Plug

Use a hammer to gently tap the plug into place, making sure the end is flush with the wall, and nothing protrudes.

4. Insert the Screw

Place the tip of the screw into the opening of the wall plug and gently turn the screwdriver clockwise. The screw should ease into the wall plug, offering resistance as it bites into the plastic.

Fixing a Larger Hole With Automotive Filler

1. Bore a Larger Hole

Using a drill, bore a new hole to extend the diameter of the stripped screw hole. Try using a drill bit that’s the next size up. Ensure the opening is larger than the screw itself because the filler needs to have space to grip the screw.

Automotive filler is best suited to bigger openings that take lag screws and bolts.

2. Mix the Automotive Filler

Follow the manufacturer’s guidelines when mixing the filler. Find a piece of cardboard and a putty knife to blend the compounds together to activate the chemical reaction. Most automotive fillers contain putty-like ingredients that harden when mixed.

3. Fill the Hole

Using the same putty knife, scoop up the filler and press it into the enlarged hole. Depending on the size of the gap, this might take a few scoops. Smooth out the top with the wall, so it sits flush.

4. Lubricate the Screw

Using a spray lubricant, wet the end of the screw, making sure it is saturated. WD-40 is a great choice. This helps you remove the screw from the partially set automotive filler.

5. Insert the Screw

Push the screw into the wet putty, twisting it clockwise as you go. Make sure the screw is positioned in the center. The idea is that the screw makes an impression of its thread pattern in the filler as it hardens.

If excess filler spills out, push it back into the hole and smooth it with the putty knife.

6. Wait for Five Minutes

Time a gap of 5 minutes to allow the filler to start setting. Now take the screw out using an anti-clockwise motion. When you remove the screw, you should see the thread pattern inside the hole. Don’t leave it until the automotive filler fully sets, or it will cement the screw in place.

7. Let It Dry Overnight

Wait until the next day to allow the filler to completely set. When you are sure it is ready, insert the screw into the hole, allowing the thread to grip.

Other Ways To Fix a Stripped Screw Hole

There are some other ways to remedy the problem of a stripped screw hole.

Use a Larger Screw

Often, using a larger screw will sort out the issue. Choose a screw that is slightly longer and wider, and try to match the threads, so they are compatible. Screws with a lower TPI (teeth per inch) are more aggressive and bite into the hole differently.

The new screw should chew into the wood, securing the threads and cutting a wider course. This holds it in place.

Using a Hardwood Plug or Dowel

If the stick approach fails, it might be an idea to use a hardwood plug that matches the stripped screw hole size. You can buy dowels or hardwood plugs from hardware stores. Use the same wood glue to coat the edges of the plug and insert it into the wall.

Wait until the glue dries before attempting to insert a screw into the hole. Like the toothpick method, the screw should gain purchase and sit tightly in the spot.


A Job Well Done

These methods are failsafe ways to mend a stripped screw hole. Once completed, they should hold your screws in place, just like a freshly bored screw hole.

All it takes to complete these tasks is a level head and a little patience. Oh, and don’t forget some creativity.
