Rivet nuts are products that we often see and often use in our daily lives. I believe everyone knows. The threaded rivet nut and the knurled rivet nut are a kind of rivet nut. Although their usage is different, they are always rivet nuts. Today, let us see what is the misunderstanding of using threaded rivet nuts?
1. The holes of the screw and nut do not match
The screws and nuts (such as drive shaft bolts, flywheel bolts) that bear the transverse load and shear force of the machine are matched with the bolt holes to achieve transitional fit. The components should be sturdy and reliable, and able to withstand lateral forces. When assembling, no one pays attention to check. When the gap between the bolt and the bolt hole is large, still choose to install. As a result, the bolt will loosen or a cutting accident will occur.
2. One female head and multiple pads for fixing screws and nuts
During the installation process, sometimes the assembled screws and nuts are too long, so someone installs many spring washers on the bolts. In this way, the spring washers will not be uniformly stressed during the curing process, and some spring washers will break, causing the bolt to be pre-tightened. The tightening force is reduced; or eccentric load is generated, which will reduce the reliability of the bolt connection.
3. Thicken nut
Some people think that thickening the nut can increase the number of working turns of the thread and improve the reliability of the connection, but this is not the case. Conversely, the thicker the nut, the more uneven the load distribution between the threads of each circle, the easier it is to loosen the connection.
The threaded rivet nuts are commonly used nuts. We will encounter some problems and troubles during use, such as the above-mentioned misunderstandings. Therefore, when using nuts, please pay attention to the specifications to minimize these misunderstandings. www.khfastener.com
