Installing Clinch Nuts

For easy installation, the self-clinching fastener is placed in the prescribed hole in the mating sheet metal. When the fastener is pressed into the mating sheet metal, the ductile panel material flows around the clinch profile and forms a strong permanent bond in the assembly.

Self-clinching fasteners must be harder than the metal where it will be installed. Clinch nuts need to be installed into ductile materials such as steel, aluminum, or copper panels. The self-clinching nut installation process eliminates loose hardware. Loose hardware in electronic applications can cause a myriad of issues and application failure.
