How To Remove One Way Screws


One way screws, a type of security screw, are the screws most often used in safes, security gates, bolt locks, and hangings in public areas. While they're easy to install, they're much more difficult to remove.

One way screws have smooth slots that make it near impossible to grip screwdrivers onto. As their name implies, one-way screws are designed to be screwed into a surface and never removed. The left-hand sides of the screw heads are curved, so they cannot be extracted with a regular screwdriver. But with determination and a few tools, you can do it. Read the tips listed below and learn about how to remove one way screws.

If you're having difficulty getting a grip with the pliers, you may want to file two opposite sides of the screw's head and then place the pliers in those flatten edges.
