  • 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.
