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.

Your wooden construction might be strong, but is it secure?

Wooden constructions like sheds, fences, pergolas and garden rooms are popular for good reason - they balance between practicality, aesthetic and affordability. Wood offers a range of benefits:

  • A natural look that fits anywhere
  • Easy to work with
  • Cost-effective
  • Good Strength - weight ratio
  • Sustainable
  • Versatile and Adaptable
  • Natural Insulation
Your wooden construction needs security

Timber is used all over the world for many construction projects and has stood the test of time. From doors to fences, wood is one of the most commonly used, oldest and reliable of construction materials. Security Fasteners can be used across a wide range of wooden construction projects, such as:

  • Fences
  • Hinges
  • Handles and latches
  • Window frames
  • Sheds
  • Roof panels
  • Deck boards
  • Handrails
  • Steps and structural joins
  • Slats and supports
  • Climbing frames

Security fasteners can be used across a wide range of projects to improve safety, durability, and overall protection. By design, they help prevent dangerous loosening and unauthorised removal - two common issues with standard fixings.Over time, ordinary screws can be deliberately or casually loosened, especially in exposed or high traffic areas. Security fasteners remove that vulnerability, keeping components firmly in place. Handrails stay solid, steps remain stable, and structural joints hold tight.They also play an important role in reducing wear and tear from interference. Every time a standard screw is removed and reinserted, it weakens the fixing point in the wood. This repeated movement can lead to stripped holes, reduced holding strength, and eventually unstable and wobbly connections. Security woodscrews, such as Clutch head or Sentinel help prevent this cycle by limiting unnecessary interference and preserving the integrity of the material.


The long-term benefits are clear: fewer repairs, less need for replacement parts, and a longer lifespan for the structure as a whole.
Ultimately, the use of Security woodscrews improves safety as they discourage tampering, reduce the chance of theft and help ensure that components stay safe and strong.
