Removing Stripped or Damaged Screws: What to Use

Patience, and the right tools and supplies make all the difference when removing a stubborn screw that is stripped, seized or broken. 

Removing stripped screws tips

We’ve covered how to remove stubborn fasteners such as screws, nuts and bolts in the past. Here we’ll focus on 5 tools and supplies that make the job of removing a stripped screw easier. 

Penetrating Oil

Clean off corrosion, dirt or other paint from the screwhead, then apply penetrating oil to the seized thread. Penetrating oil wicks down into the thread and acts as a solvent to break down corrosion, and as a lubricant to ease the removal of the screw. Leave the penetrating oil on overnight or for at least an hour, adding an additional few drops from time to time. Next, hit the screw squarely on the head with a screwdriver and hammer to shock the threads and break them free.

Impact Driver

Use an impact driver, the ideal tool for removing stubborn screws. Impact drivers deliver a strong and abrupt combination of shock and rotation to the screw that breaks the thread free.

Butane Torch

Apply heat to the screwhead using a butane torch or soldering iron, then cool down the screw with water. The heating and cooling expands and contracts the screw, which helps loosen up the threads.

NOTE: Heating a screw might not be an option, depending on the location of the screw and the materials around it.

Drill

Use a drill bit narrower than the diameter of the screw’s threads, and drill a pilot hole down into the screwhead. Next, use a drill bit that’s the same size as the screwhead, and drill it away so you can remove the part the screwhead was holding. Finally, grip the exposed screw thread with pliers and rotate and extract it.

Screw Extractor

Drill a hole into the center of the screw, then use a screw extractor to remove it. As you drive the screw extractor into the hole, the extractor will rotate the screw from within and slowly remove it.
