Phillips Drive System: PHILLIPS SQUARE-DRIV®
One drive system with five choices of engagement
The benefits of the PHILLIPS SQUARE-DRIV® combination drive system are significant. In larger, higher torque applications where stick-fit and off-angle driving are crucial, PHILLIPS SQUARE-DRIV® is especially useful. Fasteners can be better controlled at higher torque levels for optimum clamp loads. This reduces driver bit wear and eliminates driver cam-out which can cause recess reaming, component damage/rework and operator injury. The stabilizing ribs in the recess and driver bit ensure a class leading stable fit and further help eliminate cam-out. In field service operations, versatility is the mark of the PHILLIPS SQUARE-DRIV® combination drive system. A single drive system allows the use of five different drivers: PHILLIPS SQUARE-DRIV®, PHILLIPS II®, POZIDRIV®, Square, and Generic Phillips.
