Verify whether the screw is Stripped or Seized. If a screw is Seized but not fully Stripped, you might be able to remove it more easily with these methods:
- Use the best fitting wrench. It should not be too small or too big. Verify it is seated all the way into the screw head. Typically, the short tail of the wrench grips the screw best.
- Use Percussion. Slightly tapping the wrench with a hammer into the screw head can help it seat fully into the screw head and loosen the screws seized threading.
- Use Counter Turn. Occasionally applying small amounts of "righty-tighty" force can help loosen the screws seized threading.
- Only for screws with Loctite; consider applying heat. A Heat Gun/Soldering Iron might help loosen the screws seized threading. Screws that might have Loctite will have more information on the list of screw specific articles below.
- You might be able to use a Center Punch or Spring Loaded Punch. Align the Punch inside the screw, off of the screws center, and punch it counter-clockwise.
The information below provides steps to remove stripped screws. If you are uncomfortable with performing the removal process, Melco recommends contacting and hiring a Melco Certified Technician to remove stripped screws. Some screws might allow you to use a Screw-extractor Kit to remove the screw. Others might need a Dremel tool to cut a straight line into the screw and use a Flat Head Screwdriver, or the screw might need to be drilled out and re-tapped.
