How To Remove Security Screws - A variety of security screw types


Security screws, also known as tamper proof screws, one way screws, locking screws, and more, are standard screws with a unique head, making it nearly impossible to remove with common tools. These are commonly used in the automotive and electronics industries, along with public spaces such as bathroom cubicles and secure windows to prevent tampering.

Obviously, you should always try to remove a security screw with the proper bit, as the process involved in removing a stripped security screw will be a nightmare.

If not, you may have no choice but to cut a slot in the head and remove it with a flat blade screwdriver.

For the specific type of security screws known as one way screws, we have an article on how to remove them here. How To Remove One Way Screws
