Higher torque with Raptor™ feature
When manufactured with the optional Raptor™ gripping serrations, the Penta-Nut™ can handle 20% more torque and provides more grip than any other security bolt and screw on the market.
- Radial serrations allow the center head to flex downward with torque
- Eliminates the need for a lockwasher
- Larger diameter spreads the compressive load better
