PIN-TORX Self Tapping Security Screw

As the name states, this has an internal pin within the socket which requires a special insert bit or key wrench to insert & remove. This reduces the risk of tampering by thieves or intruders undoing the screws. This design provides more clamping force.

The Hexalobular TORX inner drive facilitates a more reliable slipless fixing. Due to its 2-way reusable fixing capability, this is a useful security screw where maintenance is required.
