Spline plug ring gauge

The spline ring gauge and plug gauge can also be designed and manufactured as comprehensive gauges for simultaneously detecting the large and small diameters of workpieces. In gauge design, other components are used to assist in calibration, including positioning devices (such as shaft neck diameter), bottom holes, planes and holes related to tooth pitch, etc.

The spline ring gauge is a tool for measuring the accuracy of internal thread dimensions. This plug gauge can be divided into three types: regular coarse thread, fine thread, and pipe thread. Thread plug gauges with a pitch of 0.35 millimeters or less and a second level accuracy or higher, as well as thread plug gauges with a pitch of 0.8 millimeters or less and a third level accuracy, do not have end gauges. Thread plug gauges below 100mm are taper shank thread plug gauges. A double threaded plug gauge with a diameter of over 100 millimeters.
