The thread is the ridged part of the screw or bolt shaft that allows it to be screwed into something with contrasting thread. The thread for both screws and bolts comes in different standard measurements depending on where in the world you are. You can measure these with the help of the device. Obviously, it is easy to know the size of the external thread using a ruler, but no one can do it for the internal thread. Therefore, you need a specific device that will help to do this.

Using a device, you will easily Measure the Internal Thread Part Diameter with ease. But it is necessary to have full information about this. One of the most essential rules in part thread inspection is to make sure that the part threads are clean, free of burrs and other obstructions. Incomplete threads or poor form and surface finish will also cause issues and adversely affect the function of the gage and the inspection of the threaded part. Another essential point to remember is never to force a gage into the part.

If the gage stops, remove it from the part, clean, and check the part of the damage. Forcing a gage into the part not only damages the part but can also shorten the life or damage the gage. Aside from this, it is also important to note that the major diameter of the no-go thread plug gage is always smaller than the major diameter of the go thread plug gage for 60° screw threads. This is done by design to make sure that, if the no-go gage fits into the internal part thread, it means it is oversize.

A correctly designed no-go thread plug gauge should never come into touch with the internal part thread's major or minor diameter. The gages must not be forced. Other considerations that may necessitate a change to this practice are exceptionally thin or ductile materials, a small number of threads, etc. The M series metric screw threads per ASME B1.16M are different. The metric threads allow the no-go thread plug gage to enter up to two turns with the same exceptions as the unified inch screw thread.

The purpose of this allowance is to take into account the incomplete thread on the part and additional wear on the starting threads on the thread plug gage. However, you should have an appropriate device to Measure Internal Thread Part Diameter. So, find a trusted supplier to purchase such kind of product. This will ensure you get the value of your money.
