This gauge make operating efficiency improve from the double measurement to just once!
The one-way thread gauge make operational efficiency improve with just one measurement as opposed to an existing plug gauge must take a double measurement (Go / Not-Go). A passing grade is that the GO-side thread plug gauge section can be easily inserted in a tapped hole and it stops up to the end face of the gauge stopper. Can privent an inspection error, because the go side gauge is guide.
A passing evaluation is that the GO-side thread plug gauge section can be easily inserted in a tapped hole and stop up to the end face of the gauge stopper.
Measurement of threaded hole coaxiality (alignment)
Measurement of threaded hole and tapped hole
Measurement of helical (planet) tap machining allowance
Not-go side section is only 2 pitch, but removing the stopper make calibration as standard thread gauges. Removing the stopper does not need an exculsive tool.
1.Remove the stopper. 2.Measure the go side. 3.Measure the Not-go side 4.Set the stopper
