Description
As the name states, this has an internal pin within the 6-Lobe 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.
For higher torque and clamping force.
