What are Thread Plug Gages?
Plug gages are externally threaded tools used for inspecting internal threads. They verify whether female threads in components such as nuts or tapped holes meet the required specifications. They are often available in two-piece sets, which include:- Go Plug Gages: The “Go” gage should fully enter the internal thread, confirming the minimum material condition is met.
- No-Go Plug Gages: The “No-Go” gage should not enter more than two full threads to ensure the component does not exceed the maximum material condition.
What are Thread Ring Gages?
Ring gages are internally threaded tools used for inspecting external threads. They confirm whether male threads, such as those on bolts or screws, meet specified dimensions. Like plug gages, ring gages are also available in two options:- Go Ring Gages: The “Go” gage should accept the external thread and run along it smoothly.
- No-Go Ring Gages: The “No-Go” gage should not advance more than two threads, ensuring the part does not exceed the upper tolerance.
