UNC or coarse screws are the most common type and used for general purposes. By looking at the light-passing between the gauge and the part, you can, to some extent, decide about the matching of the flank angle of the thread as well. Plain ring gauges feature a smooth inner diameter and are designed for checking shafts and cylindrical parts that do not have threads or a spline cut along the surface. A thread pitch gauge is a visual checking device to identify the pitch of a threaded part and it is NOT a typical metrology/inspection device. Pitch gages are accurately notched metal blades that match the TPI of different types of threads and thread pitches. Again: a pitch gauge is only a visual comparator. It is made to the minimum dimensions of internal threads, to ensure accurate inspection. Spaced Threads - used on woodscrews, self-tapping screws, coach screws and Type 25 thread cutters.

Each type of thread or yarn is assigned a number. They are used to check the pitch of screw threads. What this means is that a wear check plug should not enter into the thread ring more than one turn on either end of the ring. For that purpose, there will be a GO sized setting gauge and a NO-GO sized setting gauge for the ring gauges. When a Wear check plug for the NO-GO thread ring is available, a separate NO-GO check plug for the ring is not necessary.
