How to Remove a Stripped Screw
For many mechanics, carpenters, and electricians, a stripped screw is an annoyance that makes maintenance and assembly tasks more difficult than they should be. A really old screw can have its head stripped if you tighten and loosen it frequently, or if you apply too much pressure with a screwdriver when you’re working on it. A stripped screw does not offer the same grip and control as a new screw, and can cause your tools to slip and potentially injuries. Here are some ways that you can remove a stripped screw.
Tools
Removing a stripped screw requires a collection of tools:
Screwdrivers. Depending on how stripped the head of the screw is, you may need to use a range of different screwdrivers to remove the screw. Make sure that they have no-slip handles and that the bits are strong and durable enough to handle the task.
Allen wrenches and socket wrench. Allen wrenches and socket wrenches come in different sizes, and can remove the stripped screw with a little bit of effort.
Drill and screw extractor. Sometimes you’ll have to use a screw extractor to remove a screw that is stripped bare of the biting bit. You can buy a screw extractor kit from any hardware store, which costs about $5 for a set.
Steps
Removing a Stripped Screw With a Screwdriver
Select a screwdriver one size smaller than the prescribed bit for the screw.
With a bit of force, slowly and carefully loosen the screw. Don’t work the screwdriver too quickly; the tool may slip and you may end up hurting yourself.
If the smaller screwdriver doesn’t work, or if the head of the screw is stripped bare, use a screwdriver with a bit one size bigger than the prescribed bit.
Removing a Stripped Screw With Wrenches
If you’re working on wood fastened with a stripped screw, you may need to remove a small part of the wood surrounding the screw so that the socket wrench will have room to bite. Be careful not to snap the screw head away from the body of the screw.
Fasten the head of the socket wrench firmly on the head of the screw.
Loosen the screw with the wrench.
Removing a Stripped Screw With an Extractor Kit
Drill a pilot hole on top of the stripped screw. The pilot hole should only be 1-2 millimeters deep. Make sure not to snap or split the screw.
Insert the extractor’s working end on the hole, and attach the T-handle on the holding end of the extractor. You may need to tap the extractor into the hole with a hammer.
Use a counter-clockwise motion to remove the screw from the workpiece.
Stripped screws can be a hassle to remove. The proper set of tools and the right methods can remove stripped screws in no time at all, so that you can replace them with new screws.
