Sti Thread Plug Gages - Unified Sizes

KATO STI Thread Plug Gages are used to check the accuracy of the tapped hole. If the tapped hole is correct, the finished thread will also be accurate when the insert is installed. It is not necessary to gage the installed insert.
You will note that both “Working Gages” and “Reference Gages” are shown tabulated. Working Gages are recommended for use with production since their greater tolerance allows for more wear.
Reference Gages have pitch diameters at or very close to basic sizes and are to be used as master gages.

NOTES:
1. The Working Gage “GO” member has a .0002 wear allowance on the pitch diameter.
2. Gaging of the tapped thread is specified because a standard gage may not freely enter an installed insert. The insert will seat itself once a bolt or screw is installed and tightened. (REF. NASM33537.)
3. KATO STI Gages comply with A-A-59158.
4. The “GO” member checks basic pitch diameters, major diameter minimum and lead. The “HI” member checks maximum pitch diameter. Minor diameter is checked separately with a graduated pin set, for example.
