  1. 1

    Drill a hole in the screw which is stuck. You will need to start with a bit which is 1/3 of the size of the screw. Drill into the screw about 1/8 inch. Remove the drill and replace the bit with the next size up. Continue drilling into the screw with increasingly larger bits until the pieces come apart. Use pliers to remove the screw from the material.

  2. 2

    Attach a screw extractor to your drill. The right size extractor will depend on the size of the screw. You will need an extractor which is 3/4 the width of the screw. Place the extractor in the hole and drill into the screw. The extractor has grooves which turn in the opposite direction of normal screw grooves, allowing the extractor to pull the screw out.

  3. 3

    Place a square head screwdriver into the hole where the screw is. Press the screwdriver into the screw and turn the screwdriver to your left. The square head might give you more leverage to get the screw out of the hole without using a power tool.

Tips and warnings

  • Wear goggles when doing this project to protect your eyes. Since the screw head is already loose, it may fly up at you.
