Screw Thread Insert STI thread plug gages are used to insure the threaded hole complies to specification normally either a 2B or 3B classification for ANSI and 4H or 5H classification for Metric The thread designation refers to the insert thread so the size of the gage for the tapped hole is larger than the nominal size

The corresponding STI tap for that particular insert has the same thread pitch of 20 threads per inch but has a larger major diameter In this example the STI tap major diameter measures 568 quot Rather than just relying on the HeliCoil spring tension to retain the insert is there any way to positively lock the insert into the housing threads
