Countersunk Half Hex Rivet Nuts have a visible 90 degree countersunk and require a pre-drilled countersunk hole to enable them to fit flush; they are inserted into a hexagon hole which eliminates the potential problem of the nut turning in the hole after installation.
They can also be called Countersunk Bolts, but please note this style should not be confused with the Reduced Countersunk Head which has only a slight countersink.
How to use Blind Rivet Nuts
Blind Rivet Nuts are used to create an internal thread in thin or awkwardly shaped materials. As they are “blind” users only need access to the front of the material, making them ideal for use within box sections, tubes and thin sheet materials.
To use a Blind Rivet Nut you need a special setting tool, which we stock alongside other rivet nut tools. The rivet nut is inserted into a pre-drilled hole, and the setting tool is screwed into the internal thread (in the rivet hole). The force exerted by tightening this compresses the body of the rivet nut, which then collapses outward and squeezes tightly against the back of the material; the setting tool is then unscrewed, leaving the rivet nut fixed in position.
