1. No TY-17 or Cutters necessary, just using one type of Torpedo thread to solve all splitting problem and reduce much more driving torque while still remaining secure holding power no matter in hard/soft wood.
2. Different helical angled Torpedo threads design always provides easy and fast driving (front thread first grabs wood surface and becomes milling cutter while later thread engaging).
3. No splits even close to the edge of the material board.
4. KTX Drive optional, drive well with KTX or SQ bits and much more torque transfer.
5. Tornado Ribs under flat head, keep fastened object surface smooth and free of tailings and burrs around the screw head.
6. The bit easily slides into the recess due to concave surface.
