Useful information

Why use wire inserts for thread repair?

When it comes to thread repair, wire inserts’ unique design affords them a number of benefits over traditional solid threaded fasteners:

  • small, lightweight design saves on space and weight
  • original thread is restored and its performance improved
  • creates threads with high corrosion- and wear-resistance.
