What are tamper proof screws?

Tamper proof screws are fasteners engineered to prevent unauthorised removal or interference. Used by manufacturers and installers across industries, they’re ideal for protecting valuable equipment, preventing theft, and maintaining product safety.

These anti tamper screws feature drive designs that cannot be turned with standard tools, making them suitable for applications such as electrical products, public fixtures, enclosures, and furniture assembly. Fastenright offers both permanent one-way and reusable tamper-resistant screws, depending on the level of security required.

 

How do tamper proof security screws work?

Each tamper proof security screw is designed with a unique drive pattern that either:

  • Prevents removal entirely (one-way or permanent fixings), or
  • Requires a specialist driver tool to remove or reinstall (reusable fixings).

Our range includes:

  • Pin Hex screws – Standard hex design with a central pin; requires a matching tool.
  • Pin TX screws – 5 or 6-lobe Torx® style drives with a security pin.
  • Sentinel and Clutch Head screws – These are one way security screws.
  • 2-Hole (Pig Nose) screws – Twin-hole design for an aesthetic, tamper-resistant finish.

These designs make it difficult or impossible to remove the screw without the correct driver, providing true tamper resistance.

 

Why use tamper resistant screws?

Anti theft screws are widely used to:

  • Prevent theft or vandalism in public areas and outdoor applications.
  • Stop unauthorised access to electrical or mechanical assemblies.
  • Maintain product safety by preventing disassembly by end users.
  • Protect furniture and fixtures that shouldn’t be easily dismantled.
  • Secure vehicle registration plates; see our number plate security screws for a dedicated solution.

Manufacturers often use these screws to ensure only qualified professionals can access or repair their products, reducing warranty issues and safety risks.

 

Choosing the right screw

When selecting anti tamper screws, consider:

  • The required level of security (deterrent vs. permanent).
  • Whether removal is ever needed for maintenance.
  • The material and finish suited to your environment.
  • The head style that meets your strength or aesthetic needs.

Fastenright stocks one of the UK’s widest ranges of tamper proof screws, including machine-thread and self-tapping options in A2 stainless steel and other finishes.

For applications requiring the highest level of protection, Fastenright supplies premium tamper proof security screws such as our Tricone® Security Bolt; a patented design with uniquely coded driver tools for maximum security and traceability. These are ideal for critical infrastructure, public safety equipment, and high-value installations.
