Pin Hex and Pin Torx Screws
Arguably there is little to choose between these two security pin screws. Both have a far higher torque rating than philips screws, meaning they can be tightened to almost any level you require without the driver insert, wrench or screwdriver breaking. That said, the pin torx screw, with its 6 lobe configuration, performs better in torque rating under strict test conditions. It is for this reason that the Pin Torx screw is often favoured by industry professionals.
