Permanent One Way Security Screws

One way security screws are permanent fixings designed for applications where removal is not required. These one way screws can only be tightened in one direction; once installed, they can’t be undone without damaging the head, making them ideal for long-term security installations.

One Way Screws

Permanent one way security screws provide a simple, effective solution for securing fixtures that should never be removed or tampered with. Their unique head design allows the screw to turn and tighten in one direction only; turning the other way causes the driver to cam-out, preventing removal.

Many of our one way screws can be installed using standard tools, while others may require a specialised security bit depending on the design. These permanent fixings are widely used in public areas, signage, safety equipment, and other applications where tamper resistance and durability are essential.

We stock a wide range of one way security screws in various materials, head styles, and sizes, with non-standard specifications available to order.

For detailed size charts, technical drawings, or advice on selecting the right permanent fastener, please contact our sales team.
