Applied to measure thread and external thread tooth pitch. The thread plug gage, through quenching processing, strong hardness, head with a magnetic. Using rotary switch can be freely adjusted. Easy to use, light and delicate, with precise measurements and simple design, which can be widely used and durable. It is useful for checking tool angle while cutting threads in metal turning lathes.
1) Measure the thread pitch
The thread Pilot Group as a template cards toothed steel thread in the measured workpiece, if not close together, the other for one, until snug.
Then mark on the thread size model is the measured workpiece thread pitch.
2) Measuring the tooth-shaped corner
The thread pitch and the measured workpiece thread model on the same thread on top of the test, then check Talia contact, if there is no gap translucent, tooth-shaped angle measured thread is correct; if there is uneven light transmission gap phenomenon, it shows the measured thread tooth shape is not accurate.

It is most useful for checking tool angle while cutting threads in metal turning lathes.
The angles on the thread cutting tool is checked on the V slots in the gauge.
