It comes in GO and NO-GO versions — the GO gauge should pass over the thread, while the NO-GO gauge should not — confirming the thread is within acceptable tolerance limits.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Which thread standard do these gauges conform to?\u003c\/h4\u003e\n\u003cp\u003eA: These gauges conform to the American Standard thread specification (ANSI\/ASME), making them suitable for use in industries across North America and wherever American Standard threads are specified in engineering drawings.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I choose the right thread size option?\u003c\/h4\u003e\n\u003cp\u003eA: Select the option that matches the nominal diameter and threads-per-inch (TPI) of the external thread you need to inspect. For example, \"5 – 8\" means a 5-inch nominal diameter with 8 threads per inch.
