Clutch 1 Way Security Screws
Clutch head security screws (one way security screws) feature a specially shaped drive, enabling them to be fastened using a standard slotted screwdriver.
The design of the drive slot ensures that they can only be turned in a clockwise direction; if the screw driver is turned anticlockwise it will not remove the screw and will instead simply “slip off”.
Clutch 1 way screws can be fitted without a special tool or insert bit, and are widely used in a variety of applications, including for example to secure number plates.
Clutch head security screws are generally classed as permanent fixings, however a removal tool is available for stainless steel clutch head screws only.
