Ther are still manufacturing tolerances to consider but … Go No-Go gauges are inspection tools used to determine if parts are manufactured within specified tolerance limits.As the name suggests, A GO gauge is intended “to go” inside the part feature being tested and it is manufactured with maximum material condition. Each screw or nut is tested in both ends of the gauge. Its name is derived from two tests: the check involves the workpiece having to pass one test (go) and fail the other (no-go).. For example, ISO 1502 sets a standard for screw threads and gauging to test them. A “no-go” is equal to a “field” because it’s only sold in a two-piece set.

The size you mentioned, .150 +.004/-.002 would require a GO pin of .152 and a NOGO pin of .154 . If this side is not able to enter the link of the chain it is good, meaning that we have dilatation less than 1%. 00 If the threaded part fits into the go end of the gauge and doesn't fit into the no-go end, it is well-made. The benefit of go no go gauges is the ease of use – they require very little skill or interpretation to use correctly. GO means your job or workpiece is OK and NOGO means your workpiece is rejected. These gauges have a go gauge on one end, a no-go gauge on the other end, and a handle with bushings. If a rifle closes on a NO-GO Gauge it means that the headspacing of the rifle has moved beyond the minimum allowed space. Like the No-Go side, the Go never checks the minor diameter of the thread feature. Gold $$ Contributor.
