How To Remove A Screw With No Head?
Removing a screw with no head may seem like an impossible task, but with some patience and the right tools, it's entirely doable. Whether you're dealing with a stripped screw, a broken screw head, or one that's been painted over, there are several methods you can try to extract it successfully.
Method 1: Using a Screw Extractor
A screw extractor is a specialised tool designed specifically for removing screws with damaged heads. Start by drilling a small hole into the centre of the screw shaft. This will give the extractor something to grip onto. Insert the screw extractor into the hole and turn it counterclockwise. The threads on the extractor should bite into the screw shaft, allowing you to back the screw out.
Method 2: Creating a New Slot
If a screw extractor isn't available, consider creating a new slot on the screw shaft. You can do this using a rotary tool with a cutting disc or a small hacksaw. Carefully cut a straight, deep slot across the top of the screw shaft. Once you've created the slot, use a flat-head screwdriver to turn the screw counterclockwise and remove it.
Another option is to use locking pliers, also known as Vise-Grips. Locking pliers can often grip the remaining part of the screw shaft tightly enough to turn it. Adjust the pliers to fit snugly around the screw, then rotate the pliers counterclockwise. This method requires a strong grip but can be very effective for stubborn screws.
If these methods fail, applying heat can sometimes help. Use a soldering iron or a heat gun to apply heat directly to the screw. The expansion and contraction from heating can break the rust or paint bonds holding the screw in place. After heating, try using the screw extractor or locking pliers again.
For screws embedded in wood, drilling around the screw with a small drill bit can loosen its grip. Be cautious not to drill too deeply, as this could damage the surrounding material. Once the area around the screw is weakened, use pliers or another method to remove the screw.
Lastly, penetrating oil can work wonders. Apply the oil around the screw and allow it to sit for a few minutes. The oil can seep into the threads, making it easier to turn the screw. After waiting, try using the screw extractor or locking pliers once more.
