The hex rivet nut around us can be regarded as one of our commonly used rivet nuts, so do you know any precautions for the thread production of the hex rivet nut ?
When we rotate the hinge rod with even force, the operator's two hands must be balanced. Don't use too much force and shake left and right. Otherwise, it is easy to tear the thread profile and cause the threaded hole to expand and appear taper.
When the blind hole thread is tapped by the operation method of exiting the tap, when the end tap is finished, use the ream It is heavy. If the tap is screwed out with a hinge rod, it is easy to produce swing and vibration, thereby destroying the surface roughness of the thread. When tapping through-hole threads, try to avoid all the taps in the calibration part, so as not to expand or damage the last few threads.
For half hex rivet nut , pay attention to the above problems when processing threads.
