- Pitch diameter is coaxial to the cylinder portion of the gage, which projects a greater cylindrical tolerance zone than any other standard center-line locator on the market.
- Pitch diameters are calibrated, (front and back), using the universal three-wire method.
- Standard gaging diameter is .200 (+/-.0001)
- Concentricity between gaging diameter and pitch diameter of thread is within .00015 T.I.R.
- Squareness of lapped seating surface to axis is within .0001
