Make it difficult for burglars with these anti-burglary screws, or 1-way screws. The screws can only be rotated to the right. As soon as the screw is stuck, it cannot be turned off. The anti-burglary screw is often used for anti-burglary strips or other parts that are attached to outside doors. After sinking the steel screws, a thin zinc chromate/zinc oxide layer is applied on top of the zinc layer. This layer is then passivated (also called 'chromated' or 'bichromatized'). As a result, the corrosion resistance of the screws increases sharply and they also look more beautiful. Note: Use the right bit!
