Rivet nut small countersunk head large countersunk head difference

Small countersunk head rivet nuts

The appearance of the small countersunk head rivet nut is similar to that of the ordinary nut, but a unique structure is used inside. It has many uses and can connect extruded aluminum profiles, thin plates, injection-molded parts, etc. The advantages of small countersunk head rivet nuts are their simple structure and ease of installation and disassembly. At the same time, because the riveting process does not require a thimble, it can reduce the drilling cost, reducing the possibility of shrinkage and hole rupture.

The main disadvantage of a small countersunk head rivet nut is that the riveting rod is in direct contact with the nut when subjected to vibration or load changes. This makes it easy to loosen the problem, and you need to check the tightness of the nut frequently. At the same time, poor thread plugging or riveting may cause the nut joint to loosen under the torque, so attention is needed to prevent related problems.

Large Countersunk Head Rivet Nuts

The large countersunk head rivet nut in the structure and the small countersunk head are different, mainly more than a countersunk head structure. Compared with the small countersunk head rivet nut, the structure of the sizeable countersunk head rivet nut is more complex to realize a better connection effect. It connects thick plates, steel bridges, and other more significant structural parts.

The advantage of the sizeable countersunk head rivet nut is that it can be up and down to realize the reversal of the rivet nut. The small countersunk head rivet nut is prone to thread plugging and loosening phenomena. At the same time, the sizeable countersunk head rivet nut is more robust in bearing capacity, ensuring the connection's firmness and long-term stability. However, due to the complex structure of the sizeable countersunk head rivet nut, special attention must be paid to the installation and disassembly to ensure the safety of the connection.

In short, rivet nuts must be selected based on different application scenarios, and the appropriate specifications and models must be chosen. At the same time, we must pay attention to installation details, inspection, and maintenance issues to ensure the connection effect and service life!
