Set plugs become out of tolerance with a front taper condition because of the ring being engaged on the front portion only, many more times than on the back portion. So contrary to normal logic, the set plug is actually given more life by more use.

STI (Screw Thread Insert) gages designed to check the accuracy of the internal thread of an STI tapped hole. Gaging the tapped hole prior to installation of the insert is critical to ensure the accuracy of the finished thread. If the tapped hole gauges correctly the finished thread will also be accurate once the insert is properly installed and seated. It is not necessary to gage the installed insert. Helical Coil ( STI ) Thread Gages include a "GO" and "HI" (NO GO) member. The working Gage "GO" member has a.0002 wear allowance on the pitch diameter. The "GO" member checks the basic pitch diameter, major diameter, minimum and lead. The "HI" member checks the maximum pitch diameter. The minor diameter must be checked separately with a graduated pin set.

Tapered Pipe Thread Gages NPT NPT Thread Plug Gages - L1 Basic Type NPT Thread Ring Gages - L1 Basic Type The taper pipe thread plug has a step at the L1 distance from its small end. When turned hand tight into the product s internal pipe thread ( do not force the gage ), the step is required to be flush with the large end of the product thread within a tolerance of plus or minus one turn. The taper pipe thread ring gage has a thickness equal to the L1 length.the ring s large end (marked face) is turned hand tight onto the external pipe thread until it stops ( do not force the gage ). to be flush with the small end of the pipe within a tolerance of plus or minus one turn. NPT L1 Basic Type one step is provided which corresponds to basic size of component. NPT L1 Limit Type Gauge has three steps. These steps corresponds to minimum, basic and maximum size of components.

Straightness, taper, and out-of-roundness must be held within 1/2 of the diameter tolerance. Tolerances for Cylindrical Plug Gages used to check the minor diameter of internal threads,.000050 and Cylindrical Ring Gages used to check the major diameter of external threads, are specified in the thread standard as Class Z..000200.000300.000400.000800 The tolerance of the gage is based on the tolerance of the part it is to inspect. The rule of thumb is to use a maximum of 10% of the part tolerance for the gages. This allows the part manufacturer to use 90% of the tolerance for their manufacturing window, as the gages are made within the part tolerance to assure quality. The 10% is split between the Go and NoGo gages. For example: If the product has a range of.499 -.500 diameter, 10% would be.0001, which split becomes.00005 (50 millionths). Looking at the tolerance chart you would use class X gages, or better. The tolerances given in this chart are to be applied to the diameter of the gage.
