Thread Gages. Working Thread Plug, Thread Ring and Thread Setting Plug Gages are manufactured to inspect the Pitch Diameter and the Functional Thread. Thread gages are used to ensure the assembly of mating parts. Unified Inch standard gages are manufactured per ASME B1.2. M Series Metric thread gages are manufactured per ASME B1.16M.

Threaded Ring Gauges for NPT Pipe Threads with Calibration Certificate To ensure accuracy of NPT pipe thread measurements, these gauges include a certificate of calibration traceable to NIST that states they’ve passed a test for accuracy.

How to Use a Thread Gage Correctly. Using a thread gage requires careful handling to ensure accurate measurements. Begin by selecting the correct gage for your thread type—either "Go" or "No Go." Go Gage: The Go gage should screw into the part without forcing. It checks the lower limit of the thread. No Go Gage: Insert the No Go gage. If it ...

A part is within tolerance if it’s easy to thread a go gauge onto the part but difficult to thread a no-go gauge more than two turns. Inspect faster by holding more than one ring gauge with a threaded ring gauge holder. Go gauges check the maximum external thread size. No-go gauges check the minimum external thread size.
