Entry Level
Fasteners offer protection from vandalism and opportunistic crime. Drivers can be purchased by the general public.
Enhanced Security
Fasteners are less Common and less Recognizable. Driver Tooling is non-standard and Harder for the general public to buy.
Medium Security
Rarer (less well-known) products. Supply of driver tooling is controlled, less readily available to buy, enhancing the security of the assembly.
High Security
Either 1-way permanent fixing, or rare Hafren patented high security products requiring specialist tooling to remove (only available from Hafren approved distributors).
Maximum Security
Highest security available. Products are either 1-way permanent fixings, or require bespoke exclusive, custom made driver tools to remove.
Hexagon socket screws manufactured with an internal pin.
This drive prevents removal with standard hexagon tools. Suitable for medium torque applications and is one of the most difficult to remove without the matching driver.
