Powercoil – 1/2″ x 14 STI NPT Bottoming HSS Tap

Description

1/2″ x 14 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.
