• Knurled Body Insert Nuts
Knurled Body Insert Nuts are used in punched or drilled holes. During insertion, the knurled body expands 360° to fill the hole, thus providing torque strength and vibration resistance. A flange forms on the backside, without any need for adjustments even in multiple thicknesses of materials. These Insert Nuts also offer
  • Wedged Heads for greater torque capabilities, especially in soft or thin materials and electrical grounding applications
  • Low Profiles
  • Large Diameter Heads, and
  • Open Ends for versatility
