How to Remove Security Torx Screws
To remove – or indeed, tighten – torx screws, you will need compatible screwdrivers. These are called torx drivers or star head screwdrivers. Use a firm grip to tighten or loosen the screw. It’s also worth noting that pin torx heads may not be compatible with all torx drivers.

One-way security screws are designed to stay in place once installed. Part of the head curves away; the section which lies in the direction that a screwdriver would be turned to remove the screw, thereby making the head impossible to grip.
How to Remove One-Way Screws
To remove a one-way screw, you will need to apply torque via a pair of pliers. This will require a firm grip and you may need to file parts of the screw head for greater purchase. Alternatively, obtain a specialist extraction tool. These can be difficult to locate, but they will remove one-way screws relatively quickly.
Spanner Screws
Spanner screws feature a distinctive double indentation in the head. These earned this model its common alternative names – snake eye screw and pig nose screw.
Common uses of the snake eye bolt include vehicle licence plates, building and vehicle grills, and public facilities.
How to Remove Spanner Screws
Spanner screws can only be installed or removed by specialised, compatible drill bits with dual pins for each hole. The bits are fitted into a spanner screwdriver with interchangeable heads.
