/self_tappiing_threads

 

Self Tapping Thread Inserts are used...

  • To improve the strength of assemblies by distributing forces from fastener over large area in base material thus improving load bearing capability
  • In materials where threads tapped directly get damaged due to torque
  • In components where, wear occurs due to frequent assembly and disassembly
