Why Are Self-Clinching Nuts The Go-To Choice in Sheet Metal Fabrication? Here's Why

In sheet metal fabrication industry, self-fastening nuts have become the standard mainstream solution for thin plate thread connection. Whether it's industrial cabinets, electrical equipment housings, home appliance casings or structural components for new energy vehicles, most manufacturers prefer self-fastening nuts to traditional methods such as direct wire tapping and welding nuts. New industry insiders often ask: How did such a small component become so dominant? The answer lies that it can effectively address the specific challenges of sheet processing while meeting the requirements of modern factories for efficient, high-quality and mass production.
Sheet metal fabrication generally depends on thin metal sheets-the thickness is generally between 0.5 and 2 mm. While these sheets are lightweight and easy to bend or shape --making them ideal for lightweight devices --they have inherent thread-threading limitations. For thicker plates, people can simply drill and tap holes, relying on a sufficient number of threaded turns to ensure a strong connection. However, the flakes lack the necessary thickness; direct tapping can produce only two or three thread turns, resulting in poor bonding. Problems such as disconnection, tooth clipping and connection failure are common during assembly and tightening. In addition, the process can lead to sheet metal indentation, warping or cracking, leading to high scrap rates, rendering the product unsuitable for use.
Before self-fastening nuts were widely used, the industry relied on welded nuts to create flake threads, but this traditional method had obvious drawbacks. Welding nuts are fixed to the surface of the plate by spot welding at high temperature, which causes the plate to warp and warp, affecting the flatness of the plate. In addition, high temperatures can damage antirust coatings-such as galvanized or powder coating-making weld points susceptible to rust and corrosion, shortening the product's lifespan. Welding can also produce defects such as slag, spatters and air holes that necessitate manual grinding and polishing. These cumbersome and inefficient steps are incompatible with large-scale automated production.
High production efficiency is an important reason for sheet metal factories to favor rivet nuts. Traditional welding involves several time-consuming and labor-intensive steps such as calibration, spot welding, cooling and grinding, which results in higher labor costs. By contrast, the riveting process is simple, fast and compatible with automated assembly lines, enabling one installation in less than a second. Withoutinstallation and finishing, the production cycles is shortened, labor and rework costs costs are reduced, and it is very suitable for modern mass production.
In conclusion, stamping rivet nuts with their advanced technology, fastness and reliability, high efficiency, high smoothness and wide compatibility provide a perfect solution to the problems of thin-walled metal thread processing industry. It replaces outdated traditional methods while balancing quality, efficiency and cost,which is the main reason why most sheet metal processing enterprises today prioritize self-fastening nuts for assembly.
