Typically caused by the inevitable rust and corrosion that occurs inside a screw hole, a stuck screw can be an incredibly frustrating thing to work with. Not only can it slow a project down, but it can throw a wet wool blanket over anybody's good mood. This corrosion effectively locks a screw into place and removing the thing can potentially destroy the screw itself or, worse yet, the material it's embedded in. Fortunately, though, there are few sure-fire methods that will help you remove a stuck screw with relative ease and minimal annoyance.

Before beginning to beat-up your screw, though, please be sure you have the correct size and type of screwdriver; the wrong one can strip the screw-head making it incredibly more difficult to remove and virtually impossible without destroying it altogether.The first and least invasive method of stuck-screw extraction is the use a little chemical manipulation. While that may sound complicated, some pretty everyday "solutions" should dissolve the corrosion that's binding your screw.

For instance, lemon juice, hydrogen peroxide and even a refreshing cola beverage can breakup corrosion and release a stuck screw. You may even go all out and reach for some rust remover at the grocery, home or hardware store (though this is both more aggressive and more expensive.Although this technique is typically the most gentle way to release a stuck screw, you must be careful not to stain or damage your material. Damage may occur where an anti-corrosive is too potent or is left soaking for too long.In either case, your anti-corrosive solution of choice should be left to soak for a few minutes.

To the best of your ability apply the solution inside the screw-hole; tapping the screw-head while applying will help the anti-corrosive penetrate deeper into the screw-hole (and will therefore loosen or release more of the screw). The more surface area you can contact with the solution, the easier the screw will come free.After adequate soaking, attempt to remove the screw. If the screw will not loosen, attempt to tighten it (you can utilize the tightening technique throughout most of the below methods. If the screw will move in either direction (even the tighter direction) the movement should break the corrosion and, effectively, set it free. If the screw still won't budge, it's time for our next method.
