Pin Pentagon Countersunk Security Screws are tamper resistant and can only be removed through the use of special bits that only fit the specific drive.
These screws stop vandals or thieves from purchasing standard security bits in tool shops, as the security machine screws offer high security due to the tool required.
At Fastenright, we only supply the tools to customers who have purchased the screws from us as an added security measure.
Due to the countersunk head, the machine screw will sit flush in the surface of the material it’s placed in. They’re also typically used to be covered by a cap or piece of wood – thus improving the security features of the screw.
Often used to maintain security in retail, computers, public transport and more, these parts are becoming more and more popular.
