If you have ever patched and repainted a room after rearranging furniture or taking down shelving, you know the frustration of dealing with leftover wall anchors. Those tapered plastic plugs, also known as drywall screw anchors, serve an important purpose by allowing you to hang heavy items on drywall without needing a wooden stud. But when it comes time to remove them, they often refuse to budge. A clever internet hack suggests using an ordinary wine corkscrew to pull them out. This method actually works, but only under the right conditions. Before you try it, it helps to understand what type of anchor you are dealing with and how the corkscrew interacts with it. For a broader look at anchor types, read this comparison on Understanding Hollow Wall Anchors Comparison to see how different designs perform in various wall materials.
Threaded vs Non-Threaded Wall Anchors
Not all wall anchors are built the same way. The two main categories are threaded anchors and non-threaded anchors, and the corkscrew method will only work on one of them. Threaded wall anchors have coarse plastic threads that bite into the drywall as you screw them in. They are wider, stronger, and typically have a head that accepts a screwdriver or driver bit. Because both the anchor and the corkscrew are inserted with a clockwise motion, attempting to use a corkscrew on a threaded anchor will simply drive it deeper into the wall. If you have this type, skip the corkscrew and use a screwdriver instead.
Non-threaded anchors, on the other hand, are tapped into the wall rather than screwed. They have smooth sides and rely on friction and expansion to stay in place. These are the anchors that give homeowners the most trouble during removal because there is no screw head to grab onto. The corkscrew method was designed specifically for this type. To tell them apart quickly, look at the visible end of the anchor. If you see a round hole, it is non-threaded. If the center accepts a driver bit like a Phillips or flathead screw, it is threaded.

How the Corkscrew Method Works
The logic behind this hack is straightforward. A corkscrew is designed to penetrate and grip a dense material so you can pull it out with leverage. When you thread a corkscrew into the center of a non-threaded wall anchor, the spiral tip bites into the plastic and creates a firm grip. Once the corkscrew is embedded deep enough, a steady pulling motion extracts the anchor from the drywall with minimal damage to the surrounding wall surface.
In the original test conducted by Family Handyman, a standard wine corkscrew successfully removed a large non-threaded wall anchor in under 30 seconds. The key is to apply light pressure while turning and to stop after the corkscrew has penetrated about one inch into the anchor. Pulling too early or twisting too far can cause the corkscrew to slip or the anchor to break apart inside the wall. If you are working on walls that may be near structural elements, it pays to understand what lies behind the drywall first. This guide on How To Remove A Load Bearing Wall explains the kind of planning that goes into working with wall structures safely.
Step-by-Step Removal Process
Follow these steps to remove a non-threaded wall anchor using a corkscrew:
- Identify the anchor type. Look at the center of the anchor. If it has a round hole with no metal or cross shape, it is likely non-threaded and safe for this method.
- Position the corkscrew tip. Place the tip of the corkscrew directly into the center hole of the anchor. Hold the corkscrew straight so it enters the anchor evenly.
- Turn slowly with light pressure. Rotate the corkscrew clockwise while applying gentle forward pressure. Do not force it. Let the spiral do the work.
- Stop at one inch depth. Once the corkscrew has penetrated about one inch into the anchor, stop turning. Going deeper risks pushing the anchor through the drywall or breaking it.
- Test the grip. Give the corkscrew a few light tugs to confirm it has a firm hold on the anchor. If it slips, rotate slightly deeper and try again.
- Pull steadily outward. With the corkscrew handles for leverage, pull the anchor straight out of the wall in one smooth, steady motion. A slow pull reduces drywall damage.
This method works best when the corkscrew has handles that provide extra pulling leverage. If your corkscrew has a simple T-handle or winged design, you will have better control during extraction.

Limitations and Anchor Size Considerations
The corkscrew hack has clear limitations. It works best on larger non-threaded anchors, typically those with a diameter of at least half an inch. If the anchor is smaller than the spiral diameter of your corkscrew, the spiral will not make proper contact with the plastic and will fail to grip. Small anchors are better handled with needlenose pliers, which can clamp onto the rim and pull the anchor free.
Another limitation is drywall condition. If the drywall around the anchor is already cracked, crumbling, or soft from moisture, pulling with a corkscrew can enlarge the damage significantly. In such cases, it may be better to push the anchor through into the wall cavity and patch the hole, rather than risk tearing the face paper of the drywall. The table below summarizes which removal method works best for different anchor scenarios.
| Anchor Type | Best Removal Method | Difficulty Level | Drywall Damage Risk |
|---|---|---|---|
| Non-threaded, large (over 1/2 inch) | Corkscrew or needlenose pliers | Easy | Low to moderate |
| Non-threaded, small (under 1/2 inch) | Needlenose pliers | Moderate | Low |
| Threaded anchor with screw head | Screwdriver or drill | Easy | Very low |
| Damaged or broken anchor | Push through cavity or cut out | Hard | High |
| Anchor in cracked drywall | Cut out section and patch | Hard | Moderate to high |
If you are working with anchors set into materials other than standard drywall, such as concrete or masonry, different removal rules apply. Those situations require tools like hammer drills and masonry bits.

Alternative Tools and Techniques
If the corkscrew method is not suitable for your situation, several alternative approaches can get the job done without excessive wall damage. Each tool has a specific use case and knowing when to switch methods saves time and frustration.
- Needlenose pliers. Grip the outer rim of the anchor and rock it side to side while pulling outward. This works for both threaded and non-threaded anchors that are partially exposed.
- Screwdriver. For threaded anchors, simply insert a Phillips or flathead bit and turn counterclockwise. The anchor will back out cleanly with very little wall damage.
- Utility knife and patch. If the anchor breaks or refuses to move, cut around it with a utility knife, remove the damaged section, and patch the hole with drywall compound and mesh tape.
- Push-through method. For plastic anchors in good drywall, use a screwdriver to push the anchor all the way through into the wall cavity. The hole left behind is small and easy to patch with spackle.
The choice of method depends largely on whether you plan to reuse the hole for a new anchor in the same spot. If you intend to install a new anchor nearby, the push-through method is the fastest option. If you want to restore the wall to a smooth finish, the corkscrew or screwdriver methods leave the smallest holes to patch.

Patching the Wall After Removal
Once the anchor is out, you will be left with a small hole that needs to be patched before painting. The good news is that anchor holes are typically small enough to fill with spackle or lightweight joint compound in a single application. Use a putty knife to press the compound into the hole, scrape off the excess, and let it dry. Sand lightly with fine-grit sandpaper until the surface is smooth, then apply primer and paint to match the surrounding wall.
For holes left by larger anchors, especially those that caused some drywall paper tear during removal, you may need to apply a self-adhesive mesh patch before applying compound. This prevents the filler from cracking or sinking as it dries. Two thin coats of compound applied with a wide putty knife produce the best results. Sand between coats for a seamless finish. If you are also dealing with mortar or adhesive residue from previous wall fixtures, the techniques covered in How To Remove Hardened Mortar From Brick Methods can help with cleaning stubborn debris from wall surfaces before painting.
Removing wall anchors does not have to be a struggle. The corkscrew hack is a legitimate tool for the job, provided you are working with a non-threaded anchor of adequate size. By identifying the anchor type, using the correct removal method, and finishing with a proper patch, you can restore your walls to a clean, smooth condition ready for the next project.
