Security Bolts

Tamper Proof Bolts

What are security bolts and why are they used?

We a comprehensive range of security bolts designed to prevent tampering, vandalism and unauthorised removal. Also known as tamper proof bolts, tamper resistant bolts and anti tamper bolts, these fixings provide effective protection for applications that are vulnerable or located in high risk environments. By restricting access, they help safeguard property, equipment and installations while providing additional peace of mind.

What levels of security are available?

Our range includes both permanent and reusable solutions, offering varying degrees of protection. Low-torque options suit general applications, while premium, high security products, such as the patented Tricone® Security Bolt, deliver exceptional resistance to forced removal. Reusable systems are operated with matching security tools, while some permanent designs require a specialist driver for installation and cannot be removed once fitted. Shear bolts provide further security by snapping off at a specific torque, leaving a featureless head that cannot be gripped.

How do I choose the right size of security bolt?

Selecting the correct bolt diameter and length is crucial for maintaining security. If the thread is too narrow or does not engage fully with the material, the fixing may be vulnerable to removal using non-security tools such as pliers. Correct sizing ensures maximum thread engagement and a secure hold. We stock a wide range of metric sizes, including M5, M6, M8, M10 and M12, to support safe and accurate installation across numerous applications.

What sizes and types are available from stock?

We maintain an extensive inventory of security bolts in different drive types, materials and head styles. Alongside our core range, we supply large-diameter anti tamper fixings up to M48, typically in Pin Hex, Pin Torx or Wave Security drives. This makes our range suitable for commercial, industrial and specialist projects requiring high strength, tamper-resistant fastenings.

Do you offer bespoke or specialist options?

Yes. We can manufacture special or made-to-drawing security bolts to meet the requirements of unique installations or high security environments. These bespoke tamper resistant bolts can be tailored in size, material, drive type and finish to suit your exact application.
