BAERfix Self Tapping Inserts


BaerFix are self tapping inserts from BAER, Germany, that are designed to cut their own threads as they are being driven into a drilled hole (self tapping). This provides a secure and high strength anchor in the parent material.

BaerFix inserts do not require special tools for tapping.



BaerFix is typically used for thread repair and thread reinforcement.

Thread Reinforcement

  • Reinforces and increases the pull-out strength especially in materials with low shear strength
  • Provides a better balance strength distribution
  • Greater effective shear surface
  • Protection against wear of thread
  • Higher corrosion resistance
  • Helps in reduction of weight and space thus minimizing total cost

Thread Repair

  • Facilitates the repair of damaged or worn threads
  • Salvages rejected parts while maintaining the original thread size
  • Increases pull-out strength of the thread
  • Corrosion resistance
