How to Get Out a Broken Screw
To remove a broken screw, there are several methods you can try.
One option is to use a screw extractor, which can be used with a power drill to remove stripped screws.
If you don’t have a screw extractor set, you can try drilling through the screw with high-quality drill bits for metal to destroy it.
Another tool you can use is the Nejisaurus screw removal pliers, which have a curved mouth and serrations to bite into the screw head.
If you don’t have specialized tools, you can use a flathead demolition screwdriver and a hammer to cut a new groove into the remains of the screw groove and carefully turn to remove the screw.
Additionally, there are methods to address screws that are stuck due to rust or temperature-related reasons.
The shock & awe method involves using penetrating/lubricating oil, a hammer, and a screwdriver to loosen the screw.
Alternatively, the heat & cool method utilizes a butane or propane torch to heat the screw and then allows it to cool before attempting removal.
For screws with no head, methods such as using a screw extractor, an impact screwdriver, or the destruction method are recommended.
In certain cases, welding a nut onto the exposed threads of the screw can be used to turn it into a bolt and remove it with a wrench or pliers.

Reasons For A Stuck Screw
When dealing with a broken or stuck screw, there are several common reasons why it can be difficult to remove. One of these reasons is rust, which can cause screws to get stuck over time. Additionally, the threads inside the hole can adhere to the screw, making it challenging to remove. Another issue is a stripped screw head, which can occur if the screwdriver is misaligned or if the wrong type or size of screwdriver is used. It’s also worth mentioning that using the wrong head type, such as tightening Phillips screws with a JIS screwdriver, can cause damage to both the screw and the tool. Understanding these reasons is important in order to find the proper solutions for safely removing the broken screw.
Proper Screwdriver Technique
One of the key factors in avoiding a stuck or stripped screw is to use the correct screwdriver technique. Power drills, while convenient for many tasks, are not recommended for driving screws as they can easily strip the screw heads. It is best to tighten screws by hand using a properly fitting screwdriver. Choosing the right size and shape of screwdriver is crucial to prevent stripping the screw head. Specifically, when dealing with JIS screws, which are commonly found in Japanese products, it is important to use JIS screwdrivers designed specifically for these screws. Applying torque with a Phillips head screwdriver on JIS screws can lead to damage. By using the appropriate screwdriver technique and tools, you can reduce the risk of a stuck or stripped screw.
Tools For Removing Stripped Screws
When faced with a stripped screw, there are several tools available to help you remove it. Screw extractors are useful devices that can be used with a power drill to remove stripped screws. These extractors are designed to grip onto the stripped screw head and allow you to turn it counterclockwise to remove it. If a screw extractor set is not available, there is an alternative method you can use. By drilling through the stubborn screw with high-quality drill bits for metal, you can effectively destroy the screw and then remove it. This method requires patience and caution, as it involves drilling through the screw at a slow speed until it can be removed by fingers or pliers. These tools can be invaluable when it comes to removing stripped screws and getting the job done.
Screw Removal Pliers And Drill Bits
One company that has been producing innovative tools specifically designed for screw removal is Engineer. They have a product line called Nejisaurus, which includes screw removal pliers and a collection called the Nejisaurus Bazooka, consisting of drill bits and a handle for countersunk screws.
The Nejisaurus screw removal pliers have a curved mouth and serrations that allow them to bite into the screw head, making it easier to remove.
The Nejisaurus Bazooka includes wider drill bits that can work with worn screw heads. To use the Bazooka, simply choose the drill bit that fits the stuck screw, place it in the bazooka grip, and twist to remove the screw. If the screw head is stripped, you can also try tapping the drill bit with a hammer before twisting.
These tools provide a practical and effective solution for removing stuck screws.
Techniques For Removing Stuck Screws
When it comes to removing stuck screws, there are several techniques that can be employed.
One popular method is the shock & awe method, which involves using penetrating or lubricating oil, a hammer, and a screwdriver.
- Start by spraying the stuck screw with oil and allowing it to soak.
- Then, give it a few sharp whacks with a hammer before attempting to turn it with a screwdriver.
The shock and vibration from the hammer blows, combined with the lubricant, can help loosen the screw and facilitate its removal.
Another method is the heat & cool method, which is suitable for screws that have seized due to “cold welding” or thermal expansion.
- Using a butane or propane torch, heat the stuck screw for 30-45 seconds, let it cool, and then try to remove it with a screwdriver.
If the screw remains stuck, you can try the shock & awe method once again or move on to other techniques.
Removing A Screw With No Head
Dealing with a broken screw that has no head requires a different approach. There are a few methods that can be used to successfully remove these types of screws.
One option is to use a screw extractor, which is a specialized tool designed specifically for this task.
Another option is an impact screwdriver, which utilizes a rotational force to break loose the stuck screw.
If these tools are not available, you can use the destruction method. This involves using a power drill and top-quality drill bits for metal. Start by selecting a drill bit slightly smaller than the screw shaft and drilling into the screw at a slow speed. Continue drilling until the screw can be removed with fingers or pliers.
For hardened steel screws or screws too small for conventional methods, hollow screw extractors can be used. These extractors cut a hole around the screw, allowing it to be removed along with the wood it is stuck in.
Lastly, if the screw has a protruding shaft, you can use a welding device and a nut to remove it. Simply find a nut that fits the screw shaft, twist it onto the exposed threads, and weld it in place. Once the nut is securely attached, it can be grasped with pliers or a wrench to twist and remove the broken screw. This method can be used for both hardened steel screws and softer metals.
In conclusion, dealing with a broken or stuck screw can be a frustrating experience. However, by understanding the reasons behind a stuck screw and employing the right techniques and tools, it is possible to remove even the most stubborn screws. Remember to use the correct screwdriver technique, choose the right tools, and consider alternative methods depending on the specific situation. With patience and the right approach, you can successfully remove a broken screw and complete your project without any further hassles.
