Features:

- Made of stainless steel, rust and wear resistant, durable.

- It is useful to check the tool angle when cutting threads on a metal lathe.

- Check the angle on the thread cutting tool on the V-groove of the gauge.

- It is 55 Degree & 60 Degree Thread / Screw Pitch Gauge gage with lock up device.

- Thread is an inch thread with a profile angle of 55 degrees and a flattening height of H / 6. G represents cylindrical thread.

- METRIC thread is also known as international metric thread. Metric thread has ordinary thread (tooth angle 60 °); Trapezoidal thread (profile angle 30 °); Serrated thread (profile angle 33 °); Square thread, etc.(This product is suitable for 60 degree ordinary thread).

Note:

- Wipe the measuring surface of the feeler gauge with a clean cloth, and do not measure when the feeler gauge is dirty or metal septum, otherwise the accuracy of the measurement result will be affected.

- Insert the feeler gauge into the measured space, pull the feeler gauge back and forth, When you feel a little resistance, tighten the lock nut, and the value marked by the feeler gauge is the clearance value.
