6-32 STI-28 thread

6-32 STI-28 thread

6-32 STI-28 thread

(OP)
Is anyone familiar with a "STI" thread callout?  I have a drawing specifying it, and it also specifies a pilot diameter of .147 (for a 6-32).  Could this be a threaded insert prep callout?  The hole is in aluminum.

RE: 6-32 STI-28 thread

This is a heli-coil application.

Thanks BillPSU.  I thought it must be something like that, but I didn't have any literature handy.  I am accustomed to calling out heli-coil holes as "PER NASM33537" and the STI threw me.
