Security Fasteners: Securing Our Safety.

It’s undeniable that the world has changed considerably in the last few decades, altering the way we work, communicate, spend our leisure time and even get from A-B. Mobile phones, computers, the internet, GPS and social media are not just handy inventions which enhance the way we live, but actually in many cases shape and dictate it.

With these developments come a new set of dangers and risks that we need to protect ourselves and others from. Just in the same way that we learnt from a young age to consider our personal and physical security by locking doors, not talking to strangers or not doing and taking anything that would harm us, we have also adapted to apply this level of thinking to the new technologies and resources at our fingertips. From logging out of devices, to changing passwords regularly and covering our hands when we enter our pin numbers at the cashpoint, these security measures have crept swiftly and naturally into how we go about our daily lives.

What are security fasteners?

Not unlike standard fasteners, security fasteners’ basic function is to fasten components to their enclosures or to secure product structures together. They are used when it is important that the enclosed components cannot be tampered with or the structures easily removed, if at all, by anyone other than a specialist technician.

It is crucial that security fasteners are tamper-resistant, vandal and theft-proof; in order to maintain the functionality of the product they are part of, regardless of the environment, as they are often protecting expensive or function-critical electrical components.

How do security fasteners work?

Security fasteners are designed in various ways, primarily by incorporating innovative technology made to prevent anyone from undoing them without specialist equipment or training. Usually, the drive on these fasteners is an unusual shape and requires a non-standard drive, such as 2-hole drive security screws (known as pig-nosed fittings) that have two holes in the head which can be set at varying distance apart. Another example would be Security nuts which are designed to prevent their removal by having features such as a tapered diameter, making them resistant to gripping devices.

The drives on security fasteners require a specialist tool to fasten and unfasten which are often only made-to-order by the manufacturer, with the possibility of agreements put in place, making sure that they are supplied solely to the ordering customer.

In addition, it’s possible to design security fasteners to have increased frictional resistance within the bolt, limiting rotation and thus making it substantially more difficult to allow the nut to be loosened and removed.
