Request Information
Closed End Insertnuts eliminate leakage past the threads from either side of the application.
  • Wedged Head for greater torque capabilities, especially in soft or thin materials & electrical grounding applications.
  • Low Profile
  • Large Diameter Head
  • Knurled Body for use in punched or drilled holes. During insertion, the knurled body expands 360° to fill the hole, providing torque strength and vibration resistance. A flange forms on the backside, without any need for adjustments, even in multiple thicknesses of materials.

Note

Note

 N/A Inserts listed on this page have Closed Ends, as pictured, for versatility.

Grip Range can be affected by parent material density and actual hole size. Therefore, EFC suggests trial installations to determine optimum grip.
