Calipers. (Measurement of Thread Measuring Wires) This Standard is intended to establish uniform practices for the measurement of thread measuring wires. Solid ring gauges have a fixed construction and do not require a set plug for calibration. Using the NPT or NPTF or ANPT gages can also be simple since you only have 1 primary L1 gage that acts as both Go and NoGo using the gauge notch(s) or ring face to line up with the end of the product thread +/_ the allowable tolerance the basic thread form is within compliance. A thread ring gage is an external thread gage employed for the size control of threaded work; the means of adjustment is integral with the gage body.
