When the holidays, I replaced the buttons bolts on some of our closet, which is usually a fairly simple job. However, the buttons there are already some two decades, and several screws are often used interchangeably, and one that is very difficult to remove. Until spent a frustrating 30 minutes and was finally able to get the screw out. When I got home, I could replace them in about 10 minutes, just because I know a few tricks. Hopefully this trick can help save you frustration.
STEP 1: Bigger is better
Use a screwdriver bigger than the head of a screw that can be stored in the slot. Using too small screwdriver tip to concentrate the power in a smaller area and increase the possibility of stripping out the screw head. Many times, using a large screwdriver tip will remove the screws that seem to be stripped when using a smaller tip.
STEP 2: Hold the head of the screw
If a driver is bigger does not work, try to reach beyond the screws with pliers. In our first case, the screw head up enough to get a grip with a vise grip. The key here is to use as much force as possible; really tighten down tang. Once you have a handle on the screw head, you can either turn the knob (or beans) on the other hand, may use a set of pliers, or try to play a vise grip. It works in one screw us, but on the other hand, the screw head is too low profile to get a good grip. So if vise grips do not work, it’s time for trick # 3:
STEP 3: Cut New Slot
The first two are fairly easy trick, now we’re getting serious. Using grinding or other device with a cutting wheel, either cut a new slot in the screw head, or enlarge an existing slot. Be careful to keep your cut edge flat and perpendicular to the screw head. If you make a careless or oblique cuts, it will not engage the driver is better than the original slot. Also be careful not to cut too deep so you do not damage the material behind the screws. Fortunately for us, this technique works on our last screw.
STEP 4: Drill it Out
If all else fails, you have to drill out the screw offensive. Select drill very close to, or slightly larger than the body of the screw, and drill directly into the center of the head. Once you reach the drill over the head, the rest of the screw should break loose. In the case of larger screws, you may want to start with a small drill first, to establish a pilot hole.
This is the fourth of the most useful tricks to remove the screws using tools you probably already have around the house. In the case of large bolts, especially in automotive applications stubborn, you can buy a kit drilling screws, which drill into the screw rotates to the back and tried to open the lid as it was.
I hope these tips can be useful to save frustration. Good luck!
