75° Thread Plug and Ring Gauge

The 75° Thread Plug and Ring Gauge is used to measure the accuracy of external thread dimensions, with one piece at the through end and one piece at the end. The stop ring gauge has grooves on the outer cylindrical surface. When the size is above 100 millimeters, the threaded ring gauge is of the double shank threaded ring gauge type. The specifications are divided into three types: coarse teeth, fine teeth, and pipe threads. Thread ring gauges with a pitch of 0.35 millimeters or less and higher than level 2 precision, as well as thread ring gauges with a pitch of 0.8 millimeters or less and level 3 precision, do not have a stop end.

75° Thread Plug and Ring Gauge is a tool used to measure the outer and inner diameters of threads. The following are the instructions for use:

1. Determine the model and specifications of the thread gauge, and select the appropriate specifications.

2. Adjust the zero position of the thread gauge: Place the two contact pins of the thread gauge on a flat surface and gently rotate until the reader returns to zero.

3. Place on the thread of the test object: Place the two contact pins of the thread gauge on the thread of the test object and keep them as perpendicular as possible to the thread.

4. Rotate and read: Slowly rotate the thread gauge while observing the reader, and record the maximum and minimum values. Calculate or compare data as needed.

5. Cleaning and maintenance: After use, the thread gauge should be cleaned and maintained to avoid damage or affecting accuracy.

It should be noted that when using thread ring gauges, stability, accuracy, and caution should be maintained to avoid errors or damage to the tested object. In addition, relevant safety operation norms and standards should be followed to avoid unnecessary accidents.
