About this item:
- 1/2" x 20 STI UNF Intermediate Tap
- Unified National Fine (UNF).
- 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.
