Pin Torx security screws (also known as Resistorx  and Star Drive Pin screws)) and the high security TorxPlus range are virtually impossible to remove without the special matching screwdriver. These anti tamper security screws feature a central pin in the Torx socket which prevents the use of a standard Torx key

The new high security Torx-plus system incorporates a 5 lobe head design (the standard Resistorx head features 6 lobe design). Increased security is achieved with the Torx-plus system by restricting the availability of drivers. All screws are made in A2 stainless steel and are suitable for internal and external applications. Supplied in box quantities of 100.
