Fine Finish Blind nuts (BF™/BFS™) for high-voltage applications where metal chips and conductive fines could result in breakdown or arcing.
  • Designed for sensitive applications where metal chips cannot be tolerated
  • Oversized mounting holes to provide better performance in soft material
  • Large flange design provides greater bearing surface
