About this item:
- 1/8" x 27 STI NPT Bottoming HSS Tap
- National Pipe Taper
- HSS Bottoming Lead 3B Tolerance Screw Thread Insert (STI) Tap.
- PowerCoil wire thread inserts are installed into oversize tapped holes.
- Only PowerCoil STI (Screw Thread Insert) Taps are suitable for use with PowerCoil Wire Thread Inserts.
- 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.
- Bottoming Taps have a lead of two threads and are used to ensure minimum thread run-out when tapping to the bottom of a blind hole.
- Bottoming Taps are typically preceded by the use of a Taper or Intermediate Tap.
