Hexagon head, steel screw.


  • 5/16” Hex headed screw with blade driver slot for ease of installation.

  • Extra strength and smoother engagement.

  • More threads per screw and increased torque strength.

  • Thicker, stronger shaft.

  • Shoulder prevents jamming into housing.

  • Exceeds SAE J 1508 specifications.


Stainless steel band.


  • Arcial Slots – More steel between perforations for added strength and smoother worm-gear engagement.


High standard circumferential pressures.


  • Even distribution of sealing pressure with no excessive pressure points.

  • Higher sealing pressure with lower applied torque.
