clutch-head-screw-head-detailWhen using these Clutch Head anti tamper screws, you won`t need any special tools, as these screws are installed using a standard, flat-bladed screwdriver.

The head of the screw features a clockwise drive face, which allows the screw to be installed with a conventional flat bladed screwdriver.

But if an attempt is made to remove the screw again, the anti-clockwise movement of the driver blade on the screw head, causes it to simply slip off the chamfered reverse face - making it extremely difficult to remove the screw once installed.


These low cost security screws are the original type of One-way Security Screw, which has been proven over many years.
