When you’ve chosen the tool you want to use, you can follow one of the following steps.

Using the Extraction Tool or One Way Screw Remover

Step 1: Look for an extraction tool. While in this step, you need to know that they are not easy to find nor are they cheap. Also, the hardware staff may or may not tell you that this tool does give 100% guarantee to work. It doesn’t work especially when the one way screw is driven into a solid wood with a power driver.

Step 2: Once you have bought one, place the two steel pins of the extraction tool into the slots which you can find on the head of the one way screw.

Step 3: Turn the extraction tool the way you would turn a regular screwdriver.

Step 4: Once the one way screw has come right out, put it aside to avoid creating any accidents.


Using Locking Pliers

Step 1: Buy a locking plier or get one from your toolbox. You have to know that this is one of the easiest alternatives in removing one way screws, but it does not completely guarantee success. Locking pliers don’t work if the screw has a rotating sleeve or a recessed flat head as the plier will not be able to have a good grip.

Step 2: Lock the pliers around the one way screw.

Step 3: Once you have a good grip around the screw, firmly grip the pliers and turn it around. This will remove the screw from its place.

Step 4: The screw will come right off. When it does, put it aside.


Using Standard Screwdriver

Step 1: You probably already have a screwdriver. Prepare it beforehand.

Step 2: Drill a slot in the head of the one way screw. Make sure that the result looks more or less like a flathead screw.

Step 3: Once a there’s a flathead slot in the screw, you can fit your standard screwdriver into it.

Step 4: Remove the screw using your screwdriver. Then, put the screw aside.


Using a Screw Extractor

Step 1: Use a drill to create a hole into the screw’s head. Make sure that you don’t make a hole that’s too big-- about ¼ the width of the screw head is enough.

Step 2: Fit a screw extractor on the hole you’ve created.​

Step 3: Turn the screw extractor to remove the screw.​

Step 4: Put the screw aside.​


Using a center punch

Step 1: Place the center punch on the one way screw’s sloped portion.

Step 2: Use a hammer to rap the center punch repeatedly in the screw head. Doing so will make the head rise above the surface.

Step 3: When you see a part of the screw away from the wall, grab it with your locking pliers and remove the screw.

Step 4: Set the screw aside.


Removing One Way Screw Tips

To make the job easier, here are some tips that you can use:

  • When you’re using locking pliers, but you can get enough grip, you can use a rotary grinder or a coarse file in flattening the screw’s two opposite edges.
  • It’s better if you use a rotary tool or a hacksaw instead of a drill in creating a new slot in the head of the one way screw.
  • After you hammer a center punch on the head of the one way screw, you can also use the standard screwdriver to remove the screw.
  • Also, remember not to make hard hammer blows on the center punch as it will probably lead you to slipping and missing your mark.
  • Be careful with your fingers when doing this job. It’s better if you wear hand gloves while trying to remove the screw. However, don’t choose gloves that are too thick. They can get in the way of your operation.
  • You can also try to use a penetrating lubricant on the one way screw. Let it soak for at least 30 minutes.
