Designing with security in mind

4th April 2019


The security fastener range complements TR Fastenings’s wider catalogue of industrial fastenings and can be used alongside or instead of standard parts. The security fasteners have added features to ensure that the products and their enclosed components cannot be tampered with or become loose, causing damage or injury. They also ensure that the components within the enclosed structures cannot be removed, other than by a specially trained technician with bespoke tools.

TR’s range includes machine screws, self-tapping screws, wood screws and self-drilling screws, as well as specialist nuts and drivers. A number of different drive options are available, including pin hexagon, triangular, Kinmar, 6 lobe pin, Sentinel, Solok, Scroll, Nogo, Tufnut, Armour Ring, oval, shear and more. 

Design features of security fasteners include unusual shapes to prevent tampering, requiring non-standard drives such as 2-hole pig-nosed fittings. Also there are tapered diameters, resistant to gripping devices and increased fictional resistance within the bolt, limiting rotation and making it more difficult for the part to be loosened.

Aesthetic features such as smooth finishes mean that these fasteners can also looking good - an important consideration when used in high-end and luxury environments.

The fastenings are used across applications where the components being protected are expensive or function-critical. This could include sophisticated technology, products in high risk environments or public property which needs to be protected from theft and tampering. Applications where security products are commonly used include things like street furniture such as park benches, traffic lights and road signage, as well as transport fixtures like for car seats. 

Paul Standing, Commercial Products Manager at TR Fastenings, commented:“Security now plays a vital role all the way through the engineering process, so designing in security fasteners at the beginning of the manufacturing process ensures that products and their enclosures can be protected from risk.”
