How can I remove a snapped screw effectively?

To remove a snapped screw effectively, you can try using a screw extractor tool or drilling a small hole into the screw and using a screwdriver to turn it out. Another option is to use a Dremel tool to carefully cut a slot into the screw head and then use a flathead screwdriver to remove it. Remember to apply lubricant or penetrating oil to help loosen the screw before attempting to remove it.
