Fixed gauge is a kind of measuring tool. It is very troublesome to measure one by one using large quantities of products such as vernier calipers and dial gauges. We know that a qualified product has a range of measurements. All within this range are qualified, so people take measurements and regulations to measure.
It is the two gages that pass the check and are divided into rules and regulations. For example: M6-7h's thread pass rule is a pass rule (T) if it can be successfully screwed into the threaded hole being tested is qualified, on the contrary not required to rework (that is, the hole is small). Then use the stop gauge (Z) if it can smoothly screw into the tested screw hole for 2.5 turns or more, it is unqualified and qualified. At this time, the failed threaded hole should be scrapped and cannot be reworked. Among them, 2.5 laps are national standards, if export parts can only enter 1.5 laps (international standard). In short, compliance regulations are only qualified, but compliance regulations or compliance regulations are unqualified.
