Countersunk Head Rivet nuts provide a strong captivated thread in thin panels and in applications where only one side of the panel is accessible such as box or tube section
Available in steel and stainless steel, they can be installed into panels as thin as 0.5mm and do not suffer from the maximum hardness limitations of self-clinching nuts so are suitable for installation into hard or non-ductile panels. Requiring special tooling for installation – tools range from very low cost hand tools for low volume, to air powered automatic installation guns for high volume applications. Rivet nuts have an advantage over other captivated fasteners because they can be installed on site or used for repair work to replace a previously installed fastener that has failed. The advantage of installation from one side of the application means that access to the back of the panel is never required.
