Torx Head Security Screws are used in US and Dutch prisons as an alternative to Rawl Spikes. Using Torx Head Security Screws, mirrors can be removed for remodelling of cells using a security bit.
These 1/4" (6.5mm) screws are designed to self tap into concrete after a pre drilled hole of 3/16" (4.8mm) diameter has been created. The unique DuraVision engineered steel frame has countersunk holes so that the head of the screw recesses into the frame virtually eliminating any ligature risks.
Torx Screws and security bits are available from DuraVision and their distributors.
