Hafren Security Ratings

Security Level 1

Entry Level
Fasteners offer protection from vandalism and opportunistic crime. Drivers can be purchased by the general public.

Security Level 2

Enhanced Security
Fasteners are less Common and less Recognizable. Driver Tooling is non-standard and Harder for the general public to buy.

Security Level 3

Medium Security
Rarer (less well-known) products. Supply of driver tooling is controlled, less readily available to buy, enhancing the security of the assembly.

Security Level 4

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).

Security Level 5

Maximum Security
