Scratch resistant screws require a special tool that vandal or criminal access is not possible. Screw-resistant screws are a higher class of safety screws and usually require a lesser number of tools or require additional measures to prevent them from being removed.
One Way Security Screwdriver
One-Way Screws take their names because of their drive style. The head of the connecting element has a sleek driver designed to cause the driver to go out in the wrong direction. This makes it easy to unscrew (if not impossible) the assembly of the screws only with a standard corrugated bit, but without the relevant bits or a specially designed disassembly tool.
