3 Ways to Remove One-Way Screws

Introduction:
One-way screws, also known as security screws, are designed to be difficult to remove once installed. They are commonly used in public spaces and for securing valuable items as they prevent unauthorized access and tampering. However, there may come a time when you legitimately need to remove a one-way screw. In such situations, knowing the right techniques can save time and frustration. In this article, we’ll explore three effective methods for removing one-way screws.
Method 1: Using Pliers or Vise Grips
If the one-way screw is not completely flush with the surface, you might be able to use pliers or vise grips to remove it.
- Adjust the pliers or vise grips so that they fit snugly around the screw head.
- Apply firm pressure and attempt to rotate the screw counterclockwise.
- If successful, continue turning until the screw is fully removed.
Note that this method works best with screws that have a slightly raised head, which provides enough grip for your tools.
Method 2: Slotting the Screw Head
If a screw head is flush with the surface and you’re unable to grip it with pliers or vise grips, you can cut a new slot into the screw head.
- Using a rotary tool with an appropriate cutting disc attachment, carefully create a straight slot across the center of the screw head.
- Insert a flathead screwdriver into the newly created slot.
- Apply pressure and turn counterclockwise until the one-way screw is removed.
Be cautious while creating the slot if working around delicate surfaces or materials.
Method 3: Using a Screw Extractor
For more stubborn one-way screws or damage-free removal, consider using a specialized tool called a “screw extractor.”
- First, drill a small hole in the center of the screw head using a reverse-threaded drill bit. The drill bit should be slightly smaller than the screw’s diameter to avoid damaging the surrounding material.
- Insert the screw extractor into the hole and turn it counterclockwise. The extractor’s reverse threads will grip the screw head, increasing their grip as you apply more force.
- Keep turning until the one-way screw is removed.
Conclusion:
While one-way screws are designed to deter unauthorized removal, there may be legitimate reasons for having to extract them. With patience and the right tools, you can accomplish this task without causing damage to your property or possessions. Remember to follow safety precautions when working with tools and wear appropriate protective gear.
