One-Way
This classic one-way design installs with a standard flathead but resists removal by camming out in reverse. It's low-cost, widely available, and simple to install—but also easy to defeat with pliers, extractor tools, or modified drivers. While it provides basic deterrence, it’s not suitable where determined tampering is a concern.
