warn out screws helpp

my screws are warn out i cant take em out what can i do ? helpp

 

following measures can be helpful to you:

• Avoid making the problem worse. If the tool you are using is slipping, stop using it immediately. Further slippage will only continue to wear down the screw head and make it harder to remove. Definitely be sure you are going in the correct direction for removal, which is usually--but not always--counterclockwise ("righty tighty, lefty loosy"). Pressing down hard as you are unscrewing will help prevent slippage
• Use a manual screwdriver rather than a power drill. You will be able to put more pressure on the back of the screwdriver (to increase friction) and to go more slowly. Not all drills are strong enough to exert as much torque as you need to remove a recalcitrant screw. Some chuckless drills will actually lose their grip on the screwdriver bit if you put too much torque on them (especially in the reverse direction).
• Get more torque with a socket wrench. If you need a lot of torque because you are hurting your hand or you are not getting results, the best tool is a socket wrench, a common part of many professional screwdriver sets. This allows you to get 6 inches or more of lever arm rather than the half-inch or so a screwdriver handle produces. This greatly increases the amount of torque you can put on the screw for a given amount of hand pressure.
• Use a screw extractor. The right tool for the job, assuming the screw head is worn but intact, is called a "screw extractor". This is essentially a screwdriver or screwdriver bit which has strong, rough metal threads right on the tip. These are intended to burrow into the metal of the screw head and get stuck there so you can put some torque on it.


1. Use a screw extractor like a normal screwdriver to remove the screw. Be sure to go slowly, and press down hard enough to prevent slippage and engage the burrowing threads.
2. If the screw extractor can't get a grip, you may need to drill a small hole into the screw head. You will need a drill bit that is designed for drilling metal; a wood-drilling bit won't survive. Be careful! If you drill too far, you will destroy the head entirely or make it fragile enough that it will snap off, making it even harder to get the screw out. Given the nature of what you are drilling, pieces of metal may suddenly come flying out of the assembly, so wear eye protection!
3. There is also a multi-spline type of screw extractor. The multi-spline extractor is like a hex nut with splines instead of threads on the inner bore. The multi-spline extractor fits over the head of the screw and over any projecting stud. The internal splines (teeth) engage the rounded head of the screw. Tap the extractor gently into place and turn it with a socket wrench. The multi-spline extractor is good for Torx and Allen head screws if the cylindrical body of the Allen screw is exposed. The multi-spline extractor is typically described as "Bolt extractor 5-piece set".

• Try a different screwdriver. If you don't have a screw extractor and don't want to try to get one just yet, you can try to use a different screwdriver or screwdriver bit. A screwdriver with a bigger head may help. Some screw heads can accept either a slot or a cross-head (e.g. Phillips) screwdriver. You may have some luck trying the other kind. If you have them in your screwdriver set, you might also try a Robertson (square), Allen (hexagonal), or Torx (six-pointed star) bit, depending on the shape of the hole you have. You may have some luck if you experiment with sizes.
• Tapping the screwdriver into place with a hammer may be helpful. Tap it with a hammer, but be careful and gentle as excessive force will destroy or remove the head of the screw.
• Drill out the entire screw as a last resort, and only if the screw is holding together metal objects. If all else fails, it is possible to drill out the existing screw with a power drill and bit of the same size as the screw's shaft. This will most likely remove the existing thread. Possible solutions at this point:


1. Replace old screw with a self-tapping (thread-forming) screw of slightly larger size.
2. Use a nut and bolt instead. If desired, weld the nut to one of the metal objects to create a stationary, threaded mount.
3. If the screw was large enough, install a HeliCoil insert.

• Often placing a broad, flat rubber band between the screw and the screwdriver will yield good results if firm pressure and slow rotation is used. The rubber band acts to fill in the space that the screwdriver cannot grip.

Caution- drill use should be done very carefully and it would be better if you call a dell technician. At least they will provide you a replacement if any damage is done by themselves.

 

what i usually do is put something on the palm of my hand so the screwdriver isnt painful... be very careful... and apply a LOT of force down on the screw. you can use your other hand to turn it with a pair of small pliers, or the same hand. You MUST have a good precision screwdriver, the cheap kind will quickly turn into a useless piece of metal like the screw

if that fails, the best thing you'll be able to find in your own home for this is a hobby knife. the tips always break off anyway. if the blade snapped at the right angle, you can actually carve indents back into the screw head, at least enough for the knife blade to get a grip. It works because if you've already routed the screw head, the metal on the inside is softer so the knife will cut it.

like I said this only works for me with a broken tip. normally the angle of the blade is too narrow, so dont even try it, its likely to slip or break in a more dangerous way.

 

if EVERYTHING else fails, you could probably find access to the screw post inside your notebook and break some part of the screw/bolt in half with a pair of wire cutters.

 

Something to add: (Good to know before it is too late )

• Use the right size of your screwdriver. Their sizes are not printed on them just for fun. Every screw needs the right size of screwdriver (e.g phillips screwdrivers PH0, PH1, PH2 etc.). If the one you are using is too small, you will wear the screw-head out, as if you are using a screwdriver that is too big, because the grip is far away from optimum. Of yourse you can unscrew a screw with a wrong screwdriver. But if you need to apply some force you will probably destroy the screw head.
