Higher torque with Raptor™ claw feature

When manufactured with the optional Raptor™ claw gripping serrations, the Penta-Nut can handle 20% more torque and provides more grip than any other security bolt and screw on the market.

  • Eliminates need for lockwasher
  • Larger than standard screw head spreads the compressive load better
