Tamper Resistant Sentinel® Countersunk Head Security Machine Screws

Tamper Proof Sentinel® security machine screws are available off the shelf in zinc plate with other sizes and materials available to order.

The Sentinel® Security Screw has a unique head that requires only a standard pozi screwdriver for insertion.  The drive of the Sentinel® Security Screws offer a medium security resistance against vandals and thieves at a relatively low cost.  This unique feature renders the Sentinel® Security Screw tamper proof, reducing the risk of vandals or intruders tampering or undoing the screws.

Due to the security drive design of the vandal proof tamper Sentinel® Security Screw it is suitable for higher torque applications and is a ‘1 way’ permanent fixings making it the ideal security fastener for applications where maintenance is not required.
The Sentinel® drive is an adaptation of the original Nettlefolds 'Pozi' drive, the Sentinel® drive is designed to provide a secure and permanent fixing, which can be used in high volume and inserted with a power tool.  This feature means the Sentinel® security screw is the preferred choice of customers where the application requires high volume labour intensive work.  The Sentinel® drive is beneficial in such circumstances as it has greater resistance to cam-out, compared to clutch head permanent screws.
