Tamper-proof screws, also known as vandalism-resistant screws, are designed to add a higher level of security to items that have a high risk of theft or vandalism. They use nonstandard heads that prevent people from using the standard slotted and Phillips-head screwdrivers to remove them. Examples of items that tend to use tamper-proof screws are vending machines, change machines, bathroom stall walls and security system panels. In order to install or remove many of these screws, special tools are required.

  1. 1

    Examine the screw to determine the type of tamper-proof bit that will be required. There are at least eight different configurations for tamper-proof screws, ranging from snake-eyes screws that have two small holes in the screw head to pinhead screws that have standard screwdriver shapes with the exception of a small pin in the centre of the opening.

  2. 2

    Select the corresponding bit and insert it into the hand driver.

  3. 3

    Insert the screwdriver into the screw head and rotate the driver to the left to loosen the screw. There are some screws that are reverse threaded, which means you would have to rotate right instead of left to remove them. Always check to make sure that you know what type of tamper-proof screw you are working with .
