What is what to do when screw is stripped?

When dealing with a stripped screw, several methods can help you remove it and prevent future occurrences. Here's a breakdown of common approaches:

  • Apply More Downward Pressure: Ensure your screwdriver is properly seated and apply significant downward pressure while turning slowly. This can sometimes provide enough grip to catch what's left of the screw head.

  • Use a Rubber Band or Steel Wool: Place a wide rubber band or a small piece of steel wool between the screwdriver and the stripped screw head. This can fill the gap and provide extra friction for better grip.

  • Try a Different Screwdriver: Sometimes, switching to a slightly larger or differently shaped screwdriver head can find a better purchase on the damaged screw. Consider using a impact driver for extra torque.

  • Use a Screw Extractor: A screw extractor is a specialized tool designed to grip and remove damaged screws. Follow the manufacturer's instructions carefully, as improper use can further damage the screw or the surrounding material.

  • Create a New Slot: If the screw head is protruding, you can carefully use a rotary tool (like a Dremel) with a cutting disc to create a new slot for a flathead screwdriver.

  • Drill it Out: As a last resort, you can drill out the screw head using a drill bit slightly smaller than the screw's shaft diameter. Once the head is removed, you may be able to grip the remaining shaft with pliers and unscrew it.

  • Heat the Screw: If the screw is stuck due to corrosion or thread locker, applying heat from a soldering iron or heat gun (carefully!) can help loosen it.

Prevention is Key:

  • Use the Right Size Screwdriver: Ensure the screwdriver head matches the screw head perfectly to avoid stripping it in the first place.
  • Apply Consistent Pressure: Maintain steady and even pressure while driving or removing screws.
  • Avoid Over-Tightening: Overtightening screws is a common cause of stripping. Stop when the screw is snug.
  • Use Quality Screws: Cheap screws are often made from soft metal and are more prone to stripping.
