Description:
1. [Materials]: Rivet nuts are made of carbon steel, giving them high hardness and corrosion resistance for durability and deformation resistance. Precision manufacturing ensures smooth surfaces with no burrs.
2. [Features]: These rivet nuts feature a flat head design. The nuts are made with a work-hardened surface, ensuring robust, load-bearing threads. Additionally, the half hex body rivet nut possesses a large flange, which offers enhanced strength when used in punched or drilled holes.
3. [Easy to use]: Rivet nuts require riveting tools, either pneumatic or manual. Create a hole matching the rivet nut's mounting hole size, insert the rivet nut, and use the riveting tool to secure the locking nut.
4. [Application]: Rivet nuts are commonly used in metal fabrication industries, including metal sheets and pipes. They are also widely used in the assembly of products such as cars, aircraft, trains, refrigeration equipment, switches, instruments, furniture, elevators, and decorative items.
