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
