There’s nothing more frustrating than encountering a screw that refuses to budge, despite your best efforts to remove it. You turn and turn, but it seems like the screw is stuck in place, leaving you wondering what’s going on. If you’re experiencing this issue, you’re not alone. It’s a common problem that can occur due to a variety of reasons. In this article, we’ll delve into the possible causes and provide solutions to help you overcome this obstacle.
The Mystery of the Stubborn Screw
Before we dive into the possible causes, let’s understand the basics of screw removal. When you turn a screw, you’re applying a rotational force that should, in theory, cause the screw to come out of its threaded hole. However, when the screw is stuck, this force is not enough to overcome the resistance holding it in place. There are several factors that can contribute to this resistance, including:
Threads and Thread Quality
The quality of the threads on the screw and the material it’s being removed from can play a significant role in screw removal. If the threads are damaged, corroded, or worn out, it can make it difficult to remove the screw. Similarly, if the material the screw is stuck in is soft or fragile, it can cause the screw to bind, making it hard to remove.
Friction and Adhesion
Friction and adhesion are two other factors that can contribute to a screw getting stuck. When a screw is inserted into a material, it can cause the material to deform slightly, creating a snug fit. Over time, this fit can become even tighter due to friction and adhesion, making it challenging to remove the screw.
Corrosion and Oxidation
Corrosion and oxidation can also cause a screw to become stuck. When exposed to air and moisture, metals can corrode, causing the screw to bond with the surrounding material. This can make it difficult to remove the screw without damaging the surrounding material.
Possible Causes of a Screw That’s Turning but Not Coming Out
Now that we’ve covered the basics, let’s explore some possible causes of a screw that’s turning but not coming out:
Screw Head Damage
One common reason why a screw might be turning but not coming out is damage to the screw head. If the screw head is stripped, worn out, or damaged, it can cause the screwdriver to slip, making it impossible to generate enough torque to remove the screw.
Thread Locking Compounds
Thread locking compounds, such as Loctite, are designed to keep screws in place. However, if not used correctly, they can cause the screw to become stuck. If you suspect that a thread locking compound is the culprit, try applying heat to the screw to break down the compound.
Rust and Corrosion
Rust and corrosion can cause a screw to become stuck due to the buildup of corrosive substances on the screw’s surface. If you suspect rust or corrosion, try applying a lubricant, such as WD-40 or silicone spray, to loosen the screw.
Material Swelling
In some cases, the material the screw is stuck in can swell due to changes in temperature or humidity. This swelling can cause the screw to become stuck, making it difficult to remove.
Over-Torquing
Over-torquing can cause the screw to become stuck due to excessive force being applied. If you’ve over-torqued the screw, try loosening it slightly to see if it will come out.
Solutions to Remove a Screw That’s Turning but Not Coming Out
Now that we’ve explored the possible causes, let’s discuss some solutions to remove a screw that’s turning but not coming out:
Apply Heat
Heat can be an effective way to remove a stuck screw. Apply a hair dryer or heat gun to the screw for a few minutes to expand the metal and loosen the screw. Be careful not to apply too much heat, as this can damage the surrounding material.
Use a Screw Extractor
A screw extractor is a tool specifically designed to remove stuck screws. It works by drilling a small hole in the center of the screw and then using a left-hand thread to remove the screw. Screw extractors can be purchased at most hardware stores or online.
Apply Lubricant
Lubricants, such as WD-40 or silicone spray, can help loosen a stuck screw by reducing friction and adhesion. Apply the lubricant to the screw and surrounding material, then try to remove the screw.
Use a Socket or Wrench
Using a socket or wrench can provide more torque and leverage to remove the screw. Be careful not to apply too much force, as this can damage the surrounding material.
Drill Out the Screw
In extreme cases, you may need to drill out the screw to remove it. This should be done with caution, as it can damage the surrounding material. Use a drill bit that’s slightly larger than the screw to create a hole, then use a screw extractor or pliers to remove the remaining screw fragments.
Preventing Future Screw Removal Issues
To avoid encountering stuck screws in the future, follow these best practices:
Use the Right Screwdriver
Using the right screwdriver can help prevent screw head damage. Choose a screwdriver that fits the screw head snugly, and avoid using screwdrivers that are worn out or damaged.
Apply Lubricant
Applying lubricant to the screw and surrounding material can help reduce friction and adhesion, making it easier to remove the screw in the future.
Use Thread Locking Compounds Correctly
When using thread locking compounds, follow the manufacturer’s instructions and apply the correct amount to avoid over- or under-tightening the screw.
Store Screws Properly
Store screws in a dry, protected area to prevent corrosion and oxidation. Avoid exposing screws to extreme temperatures or humidity levels.

What is the most common reason why a screw is turning but not coming out?
The most common reason why a screw is turning but not coming out is due to stripping or damage to the screw head. When a screwdriver or drill bit slips out of the screw head, it can create a rough or uneven surface, making it difficult or impossible for the screw to come out. Additionally, using the wrong type of screwdriver or applying too much torque can also cause the screw head to become stripped.
To avoid this issue, it’s essential to use the correct type of screwdriver or drill bit for the specific screw head. Apply gentle and consistent pressure while turning the screw, and avoid using excessive force. If the screw is already stripped, you can try using a screw extractor or consulting a professional for assistance.
Can a screw be stuck due to rust or corrosion?
Yes, a screw can be stuck due to rust or corrosion. When a screw is exposed to moisture, salt, or humidity, it can undergo a chemical reaction that causes rust or corrosion to form. This can lead to the screw becoming stuck or seized, making it difficult or impossible to remove.
