Removing One Way Screws: Tips and Tricks

Home Improvement

Security screws, also known as one way screws, are commonly used in safes, security gates, and public areas. They are easy to install, but much harder to remove due to their smooth slots that make it difficult for screwdrivers to grip. However, with determination and the right tools, you can successfully remove them. Here are some tips:

• Use an Extraction Tool: Finding an extraction tool may be challenging, but once you have it, removing one way screws becomes effortless. Simply place the two steel pins of the tool into the slots on the screw head and turn it like you would with a regular screwdriver.
• Create a Slot in the Screw: Another method is to cut slots into the screw head using a high-speed rotary tool with a cutoff wheel. This turns your security screw into a flathead screw, which you can then remove with a wide-blade flathead screwdriver.
• Create a Grip: You can also use locking pliers to create a strong grip on the screw head and turn it to remove. If the pliers are slipping, file two opposite sides of the screw’s head to create flattened edges for the pliers to grip.
