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
Highest security available. Products are either 1-way permanent fixings, or require bespoke exclusive, custom made driver tools to remove.

Imperial threaded machine screws with an anti-tamper security drive

For almost all fastener applications metric (or international System of Units SI as it is officially known) are the standard, after all almost every country in the world uses them, excluding of course the USA and a few imperial stalwarts. 'Inch by inch', or should I say millimetre by millimetre, we are moving towards metric, but that doesn’t help you in the meantime if you need an imperial threaded fastener, which can often be extremely difficult and expensive to source.

Hafren Fasteners can offer a wide range of bespoke made to measure security fasteners in all our most popular security drives; such as 2-Hole Pin, Pin Hex and 6-Lobe Pin. We can supply imperial threaded UNC & UNF machine screws, in all common types of head, including pan head, countersunk head, button head and raised countersunk head. Machine screws are available to order in sizes; 4-40g to 3/8"-16". Other head shapes, security drives and thread types are available.
