About this item:
- 1.3/8" x 8 STI UN Bottoming HSS Tap
- Unified National 8 Thread Series (UN-8)
- 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.
