Step 106: LOX® Recess
In 2001, John "Brad" Wagner patented LOX® recess and driver bit designed specifically for power tools. LOX® features twelve contact points, three times as many as the four points of Phillips and Robertson designs. Twelve points that transfer extraordinary torque while holding a positive engagement drive after drive. In a recent independent test, LOX® screws demonstrated more than triple the torque capacity of square.
The patented LOX® recess easily outperforms every competing drive system on the market, delivering three distinct advantages: 12 points of contact and a near zero degree drive angle, the LOX® recess is engineered to accept torque loads many times higher than competing technologies. LOX® has vertical sidewalls that transfer forces radially, keeping the bit seated and minimizing end load. The near zero drive angle (4°) optimizes torque transmission and eliminates radial stresses, dramatically increasing bit life.
The unique four offset square design four projections that effectively eliminate stripping. These projections maximize bit life while minimizing material waste. Directional stability with multiple, concentric driving surfaces are directionally stable to within less than two degrees which makes this a ideal choice where there is poor access or no direct line of sight to the fastener location.
The design also works as a tamper resistant feature and is suitable for high RPM drives (up to 2000 rpm). Because of its precise fit and evenly distributed forces, the LOX bit life is at least 5-10 times longer than competing systems. Even if the material costs are negligible, workers don't like stopping to replace worn bits. It throws off their rhythm and slows their progress. They often wait until bits are completely worn before stopping to changing them.[[br]]
