Security Screws

What are security screws?

Security screws provide a secure fastening solution for applications where standard screws could be easily removed. They feature unique drive designs that require a matching tool, making unauthorised removal difficult or impossible.

These fasteners are available in two main types:

• Reusable security screws – Removable using the corresponding security tool.
• Permanent one-way screws – Designed for single-use installation where removal is not required.

What types of security screws are available?

We supply a wide range of security screws in both machine-thread and self-tapping options:

• Machine-thread security screws are used with pre-tapped holes or paired with a security nut for a secure joint.
• Self-tapping security screws form their own threads in softer materials such as aluminium, plastics, or wood, providing strong, tamper-resistant fixings.

How do security screws help prevent vandalism, theft and tampering?

Security screws help protect installations by making removal difficult without the correct tool. Their specialised drive designs require a matching driver, preventing access with common screwdrivers or standard tools. This makes them an effective solution for securing items such as access panels, signage, electronic enclosures, and public fixtures where protection against unauthorised removal or interference is required.

Why are security screw heads difficult to remove with standard tools?

Security screw heads are designed with unique drive patterns that cannot be engaged using conventional tools. Instead, they require a specifically matched driver or bit to install or remove them. This specialised interface helps ensure that only authorised personnel with the correct tooling can access the fastening.

What sizes are available?

Our security screws are stocked in the most common metric sizes, including M4, M5, and M6 security screws. Sizes from M2 to M16 are in stock, with larger diameters available on request. Imperial threads can also be supplied where required.

Selecting the correct thread size and head type ensures a secure fit and reliable performance, whether for electronic enclosures, signage, furniture, or public infrastructure.

Each Fastenright security screw is manufactured to deliver exceptional strength, precision, and resistance to tampering. Designed for both permanent and reusable applications, they’re ideal for protecting valuable assets and sensitive equipment across industrial, commercial, and public environments.
