Broken screws are incredibly frustrating to remove, especially when it's just the screw head that's broken off. Fortunately, screw extractors make this process as clean and simple as possible. A screw extractor kit should include a number of different bits. Start with one of the two smallest bits to make a pilot hole, then tap an extractor bit into the pilot hole with a hammer until it's firmly in place. Using a pair of pliers, continue pushing down on the extractor bit but begin to turn it counter-clockwise. The broken screw should, with a little effort, begin to slide out.
