IAC Geometrical Engineers manufactures a wide range of thread gage calibration equipment and measurement instruments. Small and lightweight, it is quick and easy to use, without the complexity and cost of additional components or assembly. Units inspect fastener threads to reject those with wrong-size, wrong-pitch, short, incomplete, or damaged threads; or when features are excessively out of square or position. A common thread plug assembly (more on this later) will contain a handle with two ends, one on either side. To inspect an internal thread, both ends of the thread plug are inserted into the threaded component. The Go end of the plug is supposed to thread in; the No-Go end is not. If this test checks out, the part can pass inspection. Fastener Inspection Systems. Working thread plug and thread ring gages, in the United States, are manufactured and inspected per ASME B1.2 for Unified Inch Screw Threads and ASME B1.16M for M Series Metric Screw Threads.
