About this item:
  • 1/2" x 13 STI UNC Intermediate Tap
  • Unified National Coarse (UNC).
  • Carbon Steel Intermediate Lead 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.
  • Once the insert is installed in the tapped hole it creates the desired internal thread tolerance for the installed bolt or stud.
