How to Control The Depth of Thread Screwing?

1. The reliability of the connection. How deep is the hex rivet nut riveting into the thread hole can ensure a reliable connection? That is the most essential thing.

2. The proper length of thread. In case that the thread lines is too long, it is hard to maintain the high accuracy, also improves the cost, especially in precision parts.

3. The depth ranges of thread holes should be measured. In many cases, the depth of the thread hole is strictly controlled to prevent interference with other surfaces, particular for the sealing surface, once insert rivet nuts pierced the sealing device, it will cause the leakage of gas or oil, etc. Under the premise of a good reliability of its connection, the hex rivet nut thread should be as short as possible.

In addition, due to the form deformation caused by temperature difference, and processing errors, if the depth of thread screwing is too much, the hex rivet nuts will instead fasten not well, resulting in a lower connection effect.
