Security screws are also known as one-way screws because they can be turned in only one direction. They are called security screws because they are difficult to remove. A screwdriver is used to install a security screw, but it can not be used to remove one because the security screw's design makes the screwdriver slip out. Consider several options to remove security screws.

    First Choice

  1. 1

    Grasp the screw with locking pliers (or vice grips). Turn screw counterclockwise until it comes out.

  2. 2

    File down the opposite edges of the screw's sloped slots.

  3. 3

    Grasp screw with pliers. Remove screw by turning it counterclockwise.

    Second Option

  1. 1

    Obtain a security screw extractor. A security screw extractor works the same way as a regular screwdriver but has two pins instead of a regular screwdriver head. These pins won't slip out of the sloped slots of the screw's head.

  2. 2

    Place the security screw remover into the head of the screw.

  3. 3

    Turn the security screw counterclockwise until the screw comes out.

    Third Way

  1. 1

    Use a power drill to drill a hole into the head of the security screw. Start with the smallest bit, and work your way up.

  2. 2

    Place the bit of a regular screw extractor into the head of the screw.

  3. 3

    Carefully tap the head of the screw remover with a hammer.

  4. 4

    Turn the bit counterclockwise with a wrench to remove the screw. The upper part of a screw remover has a square shape, making it easier to attach a wrench.

    Final Option

  1. 1

    Drill off the head of the security screw, or remove it with a hacksaw.

  2. 2

    Grasp the remaining part (or shank) of the screw with pliers. Remove the screw by turning it counterclockwise.

  3. 3

    Drill completely through the screw. Place a larger bit in the drill, and drill through the entire screw again. Repeat until only small traces of the screw remain.

Tips and warnings

  • Do not break off the screw extractor in the screw. Security screw removers are not a common item and can be hard to find. They are also expensive.
