How to Remove a Stripped Screw

A stripped screw is a nuisance that can slow down any project. The simple process of screw removal, gone awry, can be a frustrating experience. Several methods can be used to remove a stripped screw. With patience, one of them will usually work.

Difficulty: Moderately Easy

Instructions

Things You'll Need:

• Screwdrivers (multiple sizes, Phillips and flathead)
• Cut-off tool
• Drill
• Screw extractor or left-handed drill bit
• Standard drill bit

1. Apply a Phillips screwdriver larger than the size intended to match the stripped Phillips screw head. Push down forcefully, at an angle, and slowly try to remove the screw. Stop immediately if the stripping worsens.

2. Attempt removal with a large flathead screwdriver. If the screw head slits come all the way to the edge of the head, use a screwdriver wider than the screw. If the slits are centered on the stripped screw head, use the largest flathead screwdriver that will fit the slot. Apply pressure and turn the screw counter-clockwise. If the screw won't budge or the head strips further, discontinue this step and move on to Step 3.

3. Notch the screw head with a cut-off tool such as a Dremel. Be sure to wear safety glasses. Repeat Step 2. If you're still unable to remove the screw, move to Step 4.

4. Drill a small hole (about 1/3 the size of the head) 1/4 inch into the stripped screw head. Insert a small Phillips screwdriver into the hole and attempt removal.

5. Use an easy-out screw extractor or a left-handed drill bit if you have one. Pushing down on the stripped screw head, slowly try to remove the screw. Be careful not too push too hard or they can break.

6. Remove the screw by drilling it out if all other methods fail. Find a drill bit the same size or slightly smaller than the screw shank. (Use a successfully removed screw to find shank size.) Drill through the head until you displace the screw. Use caution with this step, as pieces of the screw can fall. This can cause problems with electronics or machinery.
