What are security screws?

Security screws are specialist fasteners designed to resist tampering and removal using standard tools. They feature unique drive designs that require a matching tool, making unauthorised removal difficult or impossible.

Two main types are available:

• Reusable security screws – Removable using the correct security tool where maintenance access is required
• Permanent one-way screws – Designed for single-installation applications where removal is not intended

This allows businesses to select the appropriate balance between accessibility and tamper resistance.

What types of security screws are available?

We supply machine-thread, self-tapping and a wide range of security screws.

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

Alongside security screws, we also supply security bolts and nuts.

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

Security screws use specialised drive designs that cannot be removed using conventional screwdrivers or standard tools. This helps protect installations against vandalism, theft, and unauthorised interference.

Typical applications include:

• Access panels
• Signage
• Electronic enclosures
• Furniture
• Public infrastructure
• Commercial equipment

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 common metric sizes including M4, M5, and M6, with sizes from M2 to M16 available and larger diameters supplied on request. Imperial threads are also available.

Alongside standard stock, Fastenright can supply bespoke security screws and bulk quantities to support production, OEM, and project-based requirements.

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.
