Key Features

Round profile screw with traditional 'one way' clutch head that cannot be easily removed. Uses conventional slotted screw driver for installation. Ideal for permanent application where no subsequent removal is required. Suitable for surface and recessed applications. Relatively low cost fastener for low volume hand assembly.

TR Security Drivers

Our range of drivers and drive bits are available from stock but only to bona fide purchasers of TR Security fasteners and can only be purchased separately if fasteners have been previously been supplied.

Please note: Most security screws are not manufactured to DIN or ISO standards and head dimensions can vary considerably from manufacturer to manufacturer. If head dimensions are critical, please specify at time of order.
