You’ve probably already encountered this problem: a broken or rusty screw preventing you from dismantling a piece of furniture or an appliance. Don’t panic! I’m sharing with you the best tips and practical advice for easily removing a broken or rusty screw without damaging the object concerned.
Method 1: use simple techniques to unscrew a rusty screw
Before resorting to more complex methods, try these simple techniques to unscrew a rusty screw:
- Apply degreaser: spray a little degreaser on the screw and leave for a few minutes. This will help dissolve the rust and make unscrewing easier.
- Use pliers: if the screw head is still accessible, use pliers to grip the screw firmly and turn it counter-clockwise.
- Slightly heat the screw: by slightly heating the area around the screw, you can expand the materials and make unscrewing easier. Be careful not to overheat, however, to avoid damaging the object.
Method 2: extracting a broken screw with a screw extractor
If the screw head is broken, you can use a screw extractor to remove it. Here’s how to do it:
Drill a central hole: using a drill and a small drill bit, drill a well-centered hole in the shank of the broken screw.
Use the screw extractor: insert the unthreaded end of the screw extractor into the hole you’ve just drilled. Then turn the tool counter-clockwise, exerting constant pressure.
Unscrew the screw: once the screw extractor has firmly seated itself in the broken screw, continue turning the tool until the screw begins to unscrew and is eventually completely removed.
Method 3: Use a tapping screwdriver to unblock a stubborn screw
The tapping screwdriver is a very useful tool for unblocking a stuck or rusty screw. Here’s how to do it:
- Choose the right bit
Select a bit adapted to the shape and size of the screw in question. Make sure it is firmly seated in the screw head before you start.
- Position the screwdriver
Place the tip of the striking screwdriver on the screw head, ensuring that it is straight and firmly held.
- Strike the screwdriver
Use a hammer to strike the end of the striking screwdriver. The impact combined with the rotation of the tool will unlock the jammed or rusty screw.
- Unscrew the screw: Once the screw is free, use a conventional screwdriver to remove it completely.
