About this item:
  • 14 x 1.25 STI Metric Pilot Nose Tap
  • Metric Fine (Spark Plug).
  • Carbon Steel Pilot Nose Screw Thread Insert (STI) Tap.
  • Designed with economy in mind ProThread carbon steel taps allow the tapping of worn and damaged threads where a heavier duty HSS tap is not required.
  • STI Taps have a larger diameter, than standard taps, but the same pitch to accommodate the wire thread insert.
  • Pilot nose taps feature a standard diameter lead thread that engages with the damaged thread to guide the larger diameter thread cutting section of the STI tap.
  • Once the insert is installed in the tapped hole it creates the desired internal thread tolerance for the installed bolt or stud.
